    If AJ won't work it is very sick. If you are not fully backed up to an external disk do it now. Try safe boot and then try to use Disk Utility to verify/repair disk and permissions. If necessary boot from install disk to repair internal disk.

    Mr H, thanks for the reply, thanks for being there as a voice of reason/reasonableness, etc . . . yes, there is an "illness" of some variety, specifically what still remains murky.  What is interesting is that the repair disk process can be done in AJ and it declares the disk as "fine" or "repaired successfully" . . . and that part was repeated 4 or 5 times . . . .  The system is as backed up as it would need to be, but, problem being that it appears to be the FW connection that set off this latest round of KPs.  I guess there is a USB option for backing up to the ExtHD, but that is a much slower road. 

     

    I'm away from the iMac now, so it'll be awhile before I could again try to boot into Safe mode and try to repeat all of the steps I did before to get the system working as it was the last three days . . . .  But, thanks for the reminder about booting from the install disk to run repairs, etc.

    Gents:

     

    Went through a number of KPs again, Safe boot also crashed, so I again tried the AJ, but using "expert" mode and by mistake I did the "Disable NFS mounts" operation, but on the "Check SMART status" it seemed to take a long time w/o any return data showing up, but I already have SMARTReporter installed and it's still showing OK, so I don't know what was going on, if I was just too impatient, the other operations seemed to return some progress statement very quickly . . . and then like I did the first time I ran "deep cleaning" . . . and I restarted into a GUI and it didn't crash right away as it did before earlier today.

     

    Then I rebooted back into single user and ran "Applejack AUTO shutdown" . . . and it was able to run through completely without having a KP midway through . . . .  I'm leaving it shutdown for awhile, but it seems like we might be back to being able to at least use the computer as a check email machine??  I'm curious to hear why the previous comments were saying that Onyx might cause problems . . . seems like it more or less does the same thing?  Otherwise how do the daily/weekly/monthly maintenance scripts get run . . . if the computer is put to sleep the scripts don't run?  Does AJ run those scripts?  I didn't see that anywhere . . . .

    seems like it more or less does the same thing?

    AJ does these things with nothing else running, not even an OS, I do not know why, but have seen Onyx have problems on older OSX versions & older HW, but not always!?

    A high proportion of difficulties with Macs are caused by third party software particularly utilities. Sometimes these may work well in isolation but clash with something else. I have never used Onyx and know little about it but this is not the first time I have come across an Onyx user who has strange ill defined symptoms - it may be no more than coincidence and it may simply indicate a user who uses many third party utilities.

     

    I advise backing up, erasing the disk, do a clean install without importing anything including settings from earlier OSs. Do normal Apple updates but do not install any other software.

     

    Preferably do this with a totally clean disk without anything else on it. If it is duel boot and you don't want to erase a volume then don't use this Mac except to boot Tiger or Leopard.

     

    Do all this with the minimum of peripherals etc connected - ie only connect to internet.

     

    Use it for a while with this limited functionality without importing historic data etc to see if the problem still exists.

    @Mr Hillyer & BDAq:

     

    Alrighty on the 3rd party utilities . . . I'd be hard pressed to remember now if this rash of KPs started right after I ran Onyx or not . . . it has been installed for quite awhile and run manually on a monthly basis . . . .  Considering that things seemed to be more or less OK while just the ethernet was plugged in, and then instantly started crashing when I plugged in the FW ports . . . I'm sort of inclined to view this as a HW issue????

     

    The question sort of remains as to what would cause both partitions to "crash" . . . since, for example, there is no Onyx in the Xu/Lu side . . . and the Linux OS is pretty much "minimal" besides the fact that some purists consider a GUI to be "decadent" . . . or "Apple-like" . . . .  But, certainly it doesn't take too much effort to erase a disk and re-install the system, I was basing my findings that the partition that I loaded 10.4.6 onto also crashed as a sign that re-installing wouldn't change anything, but, the Ext HD was plugged into FW and if it is somehow related to FW then anything would also crash . . . .  But, not having refired the iMac yet this morning, I'm assuming that since I got through a full AJ process w/o a panic, that we'll probably run OK for awhile . . . and there just won't be any FW stuff done for a bit and we'll see if and when the next KP shows up.  I've been waiting for some Linux insight into utilities I could try on that side but so far no hints have been offered.  I hear the advice to not boot the other side, but curiosity will probably get the better of me . . . I'm just too impatient to know if the KPs have stopped over there . . . .  I'll post back in a bit . . . thanks for the sounding board and advice, certainly I've got some directions to try out . . . .

    A flakey FW device could certainly be the cause.

    @Mr Hillyer:

     

    Thanks for your stamina and perseverence . . . I did run that search, as obviously you did as well . . . one of the things that doesn't bring Google up to the top for me in terms of computer issues is the large number of results . . . many of which may or may not be relevant, especially if one doesn't know how to determine that . . . .  But, I did find that article you linked on the second page of results and it was about Tiger . . . it's sort of a synopsis of all the ideas mentioned about trouble-shooting by you, BDAq, and mr Texas . . . including the FW "cable" as being a possible source of problems.  Another thread mentioned the FW "port" . . . as a possible issue . . . .  So, I'm not the only person with a KP problem . . . I know that now . . . .  : - )

     

    Anyway, spent a few minutes fiddling around, can't remember if I said that Safe boot crashed  on reboot, so I just did a normal boot, and launched Camino and that was fine . . . then as I said I would I tried to boot into Linux, but it just booted to a black screen, possibly the mouse cursor was there but nothing else.  The I tried to boot from a Super Grub disk by holding the C key and it wasn't recognized, tried a few ways of booting the CD . . . just kept going back to OSX, so perhaps AJ has removed some "fork" or something that lets Linux boot, even though using the Option key the Linux partition shows, but for example the CD did not show . . . .

     

    But, OSX was in working order and has become the only game that is available . . . I'll run it this way for a bit and see whether other things like USB cables being re-plugged in or the ext speakers also start the paroxysms of kernel panic . . . .

    As far as I am aware AJ only affects the partition you booted from and should not alter firmware. Hence as long as you ensure you boot a Mac partition to use AJ it should not change a Linux partition. I hope you are not using Linux and OS X on the same partition.

     

    Try a clean disk with a fresh OS X install without third party software of any type including Camino.

     

    Perhaps I should mention the obvious: - you are the only person I have tried to help who is running Linux on the same computer while trying to debug OS X.

    Thanks for the follow-up on the questions about AJ influencing the Linux side, no I'm not running them in the same partition.  I'm still not finding the extra time to do a clean install . . . yet.  So far, once I got AJ run again I can use the computer w/o issues of crashing . . . haven't had the time to plug the USB extras back in yet.  I also like to get the obvious out into the open . . . thereby making it more obvious, but not surprised to hear that . . . "it's rare."  It's also rare on the Linux side to be trying to run Linux on a Mac . . . so assistance is even more rare over there . . . .  Tomorrow I might have a few spare minutes to try to promote a KP . . . .

    Well, we've (the iMac & I) have made it through almost two weeks since the last post . . . so far the only time there was a KP is when I rebooted back to OSX from the Linux side . . . but I was able to just restart w/o having to run AJ, and so far it's been OK . . . seems like it's acting like a geriatric analyst . . . things are happening, but, more or less in its own time.  The only issue now is that the Linux side seems to have broken the ethernet, rendering that side less useful . . . .

     

    In terms of this question, it's not exactly "solved" in the sense that there is satisfaction that the problem is completely repaired . . . but, it's fairly clear that the FW ports are probably the culprit . . . haven't bothered to check the USB ports yet . . . .  It basically means this unit is simply a GUI console for checking emails.  So, the question has been "addressed" and it doesn't seem like any further developments will make any difference until such time as I was able to find the time to crack open the case . . . and possibly add more RAM . . . and then, what?  replace the motherboard so that the FW port would again be operational???

     

    Anyway, I appreciate all the comments and attention, perhaps in a day or so I'll wrap this question up, and if something new pops up, we'll start a new thread . . . thanks for the conversation gentlemen . . . .

    Good to hear on the stability, but do the FW ports not work at al, or are flaky?

     

    If the latter I'd suspect the FW devices more than tyhe ports.

    @BDAq:

     

    "Tyhe ports"? . . . "tyhe ports"?  I'm not familiar with that type of port . . . do you think the tyhe ports are the cause of all of my problems?  This could be a significant development if you think so . . . how can I access and test the tyhe port function?  Is this something where DW might have a slightly higher chance of figuring out, perhaps 3.659%????  Please advise . . . .

     

    As far as the FW ports go, whether "flaky" or not working . . . I think is a fine point of distinction . . . perhaps degrading over time, certainly from the conversation here where for some time the FW was plugged into the ext HD, and the KPs came in a series but then might be OK for awhile, but then return . . . I do use the Ext HD with my MBP and so far no issues there, same with ye olde iBook (knocke on woode) . . . still to test the USB plug(s) to see if they elicit an almost instant KP response as the FW port(s) did/do . . . .  Other pans in the fire right now for the coming holiday season . . . don't know how much enthusiasm I will be able to muster in terms of breaking open the iMac entrails and fiddling with it on the hardware side . . . or just push it along until the Big Sleep takes over???  But, if you could give me any further thoughts on repairing the tyhe ports that would be great . . . the question might truly be "solved."  : - )))

    Sorry, tyhe ports should've read the ports.
