Q: PPC G5-Quad panic kernel woes

My G5-Quad had a kernel panic this afternoon.

 

Two attempts to reboot normally eventually ended in the gray  box with the well-known multilingual instructions to restart the machine, obvious signs of further kernel panics.

 

Two attempts at running applejack in safe mode (Command S) were aborted by the machine shortly after it started checking stuff with a message like "Release the PPC, we are hanging here".

 

Now it doesn't even boot in safe mode.  On an occasional try, a white screen with some small black text but does not accept any commands.

 

Then it just wont boot.  It sounds normal for a while, then the fans and pump spring into heavy action.

 

I opened the optical drive with the straightened heavy paper clip (only way to open it) and put the AHT test, tried holding the Option key, but the same behavior persists: no signal sent to the monitor, then it sounds normal for a while, then the fans and pump spring into heavy action again.

 

The first time I got the kernel panel, I was able to copy the crash report, but now I can't even get at it.

 

I'm working on my Mac Pro Quad right now.

 

I hadn't had any trouble whatsoever with the PPC G5-Quad in so long, that I've practically forgotten all about troubleshooting a PPC (getting more "senior" by the day, with brain damage caused by a series of mini strokes; diabetic type 2)

 

Any ideas as to what to do next?  I do need Classic and a PPC CPU to run a lot of irreplaceable and indispensable software that does not run on Intel machines.

 

If I can't fix this machine, I'll probably be looking for an exact replica of this (July, 2006) PPC G5-Quad. Hope to move RAM and cards, etc.

 

2.5 GHz Power Mac (PPC) G5-Quad; 16GB RAM; mutant, flashed 550MHz nVidia GeForce 7800GTX 1,700MHz 512MB VRAM; ATTO ExpressPCI UL5D LP SCSI card; Mac OS X Tiger 10.4.11 and Leopard 10.5.8 boot drives; intrusive Spotblight, Dashboard and Time Machine permanently disabled; dual 22" CRT monitors; USB wireless 'n' available but connected to the Internet via wired Ethernet; FW flatbed scanner; 2 SCSI scanners (one tabloid-size transparency scanner and a film scanner); various internal & external HDs; FW Epson 2200 and Ethernet Samsung ML-2850ND printers; 2 X Back-UPS RS 1500 XS units.

    Long time no see!

     

    Have you let it cool down & tried?

     

    Have you opened it & checked for leaks?

    Thanks a lot, BDAqua.  Great to hear from you—as I was shamelessly hoping.

     

    I'm planing on opening it tomorrow and cleaning out any dust bunnies. Difficult to move the sucker by myself in my state.

     

    Too chicken to contemplate leaks yet, but the temperatures seemed fine before it totally refused to boot again.  Hardware monitor showed the CPU heat-sinks were around 110ºF when it last read them. 

     

    But it's all possible, of course.

     

    Will report tomorrow.  I was able to communicate with a fairly local (9 mile drive through gorgeous scenery) Mac and PC outfit, it comes well recommended and the Mac technician sounds well informed.

     

    Keeping my fingers crossed.

    Hi Ramon !

     

    I am in Ukraine now, as I helping friends fight against the separatists. Anyway, is your G5 leaking ? I am not sure if that panic has to do with a leak, but I am hope, that you resolve it soon.

    Thank you, romko.  Very happy to hear from you and of your patriotic struggle.  As a direct descendant of Княз Владимип (my colorful 31st great-grandfather)  I have always been keenly interested in all that happens in Kiev.  Best wishes to you and to all Ukrainians.

     

    Don't know about any leaks yet, as I haven't gotten around to open my G5 Quad. I'm much weaker now and have to have help lifting that 75-lb glorious beast.  Monitor hardware was showing normal temperatures and normal pump RMPs right before the first crash.

     

    Thanks for posting.

    I'd disconnect the data cable from the Optical drive for a test.

     

    Is anything plugged into the FW ports?

     

    reset FW bus, same goes for USB reset...

    Reset the Firewire bus

    If your Firewire or USB isn't recognizing any device.  A solution which has worked for some whose hard drive became invisible in 10.4 was simply to follow these four steps to reset the Firewire/USB bus:

    1. Shut the machine down.

    2. UNPLUG the power lead to the computer and any firewire/USB drive or devices.

    3. leave it for 10 minutes.

    4. Connect back up and reboot.

    Thanks for your continued attempts to help, BDAqua.

     

    Wish I could get those two crash report to an engineer who can interpret them.

     

     

    No FW devices attached,  I disconnected both the external FW HD and the FW printer.

     

    No USB devices, other than the Apple keyboard, and I've disconnected that too.

     

    Hoping to have enough strength today to lift the machine so I can open it and take it to the shop. It's sitting in a nice, cool space more than a foot off the ground, bout without enough space to open it there.

    I believe all of these point to the Optical drive, or the SW for it...

    Ooooh!  That's very interesting and most useful.

     

    The optical drive and RAM would be trivial to replace; the logic board is a different matter.

     

    Thanks again, BDA.

    BDAqua, I don't want to jinx myself by speaking too soon, but it looks very much like YOU'VE SAVED MY ASSETS ONCE MORE.

     

    I gathered enough strength to lift the 75-lb G5 Quad and carried it to the kitchen table, where I opened it up, cleaned it up the interior as best I could with microfiber cloths and a battery powered computer vacuum cleaner. Had no compressed air, and I started around midnight.  There were not nearly as many dust bunnies as I expected, but there was a bit of dust in the fan blades, and very substantial blanket of dust blocking the whole intake of the GPU housing.

     

    Then I disconnected the cable from the optical drive, put the whole thing together again and attached an old, beat-up, small Dell monitor.

     

    The first attempt to start it up was utterly disappointed. No signal, and the fans kicked in like an airplane after some 30 seconds or so.  I waited a bit, tried it again twice more with the same negative result.

     

    A couple of hours later, I tried it again, and it started like a charm!  The only odd thing was that it started from my internal Leopard boot up drive, which is not set as the start-up volume.

     

    I took the opportunity to Repair Disk on my Tiger Boot volume, and Repair Permissions on it a couple of times (found nothing to repair in all tries).

     

    Then I checked the start-up volume in Syst Prefs and the regular Tiger volume was already set as my Start Up volume.as my start.

     

    It's been running under Tiger in the kitchen  for a couple of hours, running a full volume scan with ClamX.

     

    QUESTIONS:

     

    Should I try to reconnect the optical drive to see what happens, or am I better off just driving to my (very) local Fry's to buy a new one?  If the latter, do you have any recommendations, or is the cheapest one OK?

     

     

     

    Of course I'm static, since now I know the LCS is NOT leaking, pump running at 1250 RPMs, RAM is fine and so is the motherboard.         THANK YOU !

    It's still OK.  Now I'll bring it back to where it belongs and network it again.

     

    I'm puzzled.

    Well, if you want to find out if it's the Optical, you'll have to connect it & see if it fails, but if you can do without it, then it may be solved already.

    Well it's turning out to be a mysterious, intermittent problem. 

     

    In my previous post from yesterday morning, I meant to imply that I had indeed reconnected the optical drive, and it was working fine on the kitchen table, with about half a dozen reboots in normal fashion.

     

    That's when I posted yesterday.

     

     

    Then I put the machine back in its place, connected the Ethernet cable, and then the darned computer went back to the behavior of going through a normal boot process, the chimes sounded OK, everything sound fine for about 40 seconds or so, no video signal, and then the fans began to blow at full force.  Disconnected the Ethernet cable with no change. 

     

    In my frustration, I began yelling and cursing at the machine so forcefully, that my wife of 44 years came to see what was going on.

     

    It seems that my swearing and insults had an effect, because the G5 Quad started normally, and it's been working fine for some 20 hours, rebooting a number of times, powering it off for several hours while I slept, then starting again, and it continues to work so far.  Totally unexplainable. 

     

    The kernel panics have not returned at all.  At the time of said kernel panics, when  even applejack wouldn't run anymore, I got a one-time message in white type over a black screen to the effect that "Firmware Couldn't be Found" and then it would not start either in safe mode or single user mode.  That's when I posted my OP here.

     

    I have of course ran Repair Permissions and Repair Permissions a number of times, including every time that it recovered.  Now it's all copacetic.  Scratching my head.


    Thanks for all your help so far.
