Hi

Clean install on 8-core Mac Pro. Only Transmission 0.9 running. After returning to find a kernel panic screen I noticed the Airport Extreme had frozen - green light but no connection. Here's the panic log:

Does this mean anything to anyone?

    Looks like a faulty processor but I don'thave any expertise here. I'd be running Hardware test on the machine.

    That was the first thing I did (extended) - normal of course. Has never had a kernel panic on 10.4.9. Have had 4 kernel panics now, I wasn't running anything but Safari during the last one, and no new hardware installed. Have always had a Seagate USB drive connected. Will try with it disconnected.

    Had missed some SMC and EFI updates because I reverted back to 10.4.9, so installed them. Haven't had a KP since. My guess is that they were related to 10.5 changes implemented for multi-core processing. Fingers crossed. Will report back if there are any more. Have reported all KPs to Apple.

    OK..... just had nearly the identical error on a brand new 8-core Mac Pro. Was working all nice in After Effects when WHAM!... KP... thought that was pretty odd. Rebooted and immediately got the flashing power button. Decided to pull all the hard drives except the boot drive. Rebooted and machine came right up. Oh... had a G-RAID attached via FW800 as well... but wasn't doing anything with that drive.

    Here is my error report:

    I haven't had a single KP since my last post. If your MP came with 10.5 installed, I think your KPs are probably due to something different to my previous situation.

    Strangely enough, I woke up this morning to find the system had rebooted itself....due to a panic.

    Caused by the USB driver by the looks of it. Not quite sure why, as it was asleep at the time. Odd.

    By the way, for anyone really interested in kernel panics and CPU exceptions:

    Chapter 5 is very informative.

    OK.... I've been getting the flashing light and inability to boot up problem on a more frequent basis. I'm really starting to suspect a hardware issue. Here is my latest log from when the computer was unable to start up:

    4SNS/1/40000000:TM3S (second test)


    If I go in and reseat one or two hard drives many times I'm able to reboot fine.... not sure if it's an SATA bus or controller problem or something completely different. Disk Utility says all my drives are fine.

    When I started reading the posts of how others were doing with moving to Leopard, I was concerned about how folks were migrating to Leopard. I decided to take steps to make it easier to isolate any problems when I moved up. I upgraded via Apple's "Up-to-Date" DVD. When I upgraded, I put a new 500 GB drive in another bay, partitioned and formatted it like the system drive, then I copied the data from the data partition and installed Leopard on the new drive. It was not the most painless way to upgrade because I had to re-stack my system from scratch, but it ensured that I had a solid regression path and all my data is backed up. When I was convinced I was ready to complete the transition, I pulled the system drive, put the new Leopard drive into drive bay 1, put the other drive in an enclosure and stored it in a safe place. I did this on 02 Nov, and other than the usual early adopter bugs, I've had no issues or KP's. Like early Tiger, there's a lot to like, and a lot of room for improvement. Fortunately, stability doesn't seem to be an issue ... **Knock on wood**
  • 10. Re: Leopard Kernel Panic
    Doug Stringham Level 3 Level 3 (685 points)
    OK... it appears that the 1GB of RAM that Apple sent with the machine is bad. I had noticed that I had a red light on my Riser A. I pulled the Apple supplied RAM from the board and swapped it out with my Crucial RAM and the light went out. Not sure if that was causing the startup and kernel panics... I'll keep you posted.
  • 11. Re: Leopard Kernel Panic
    Opus_Maru Level 1 Level 1 (10 points)
    Bad RAM can cause fits, especially if there are no visual indicators. That would definitely cause KP's.

    MacIntouch "Bad RAM" was a good article and "must read." trouble with bad RAM and k/ps is you can have bad data written to disk as a result. Fixed the problem. Fresh OS, but I had to be careful for months with using Disk Warrior even more often.

    This is interesting. I had a few kernel panics over the past few weeks. This was on a PowerMac G5, actually a dual-CPU machine, and it panicked at exactly the same spot, in com.apple.driver.AppleUSBEHCI(3.0.3). Is this coincidence? Completely different hardware, yet the same routine that causes a kernel panic?

    I have solved this problem for me, I think. I found this forum thread:

    http://discussions.apple.com/thread.jspa?threadID=1220488&tstart=0

    A suspicion expressed in there is that kernel panics with USBEHCI in the backtrace can be related to the hub in Cinema displays. And I am using a Cinema display... Unplugging the USB cable from the display and plugging the keyboard directly into the computer seems to have fixed the problem. I haven't seen any freezes since.
