I'm afraid I don't have enough experience with this debugger to get these values with offhand commands. I could trial and error my way through figuring it out, but I'd rather get the data you expect. :) If you could give me the commands to do this, I'd be happy to type them in and get a response to you. > Is this problem reproducible?

If it comes up a certain number then it crashes, otherwise it's fine. ;) My ISO generation process might be relevant; I create a 600MB ramdisk (it used to be 512 on FreeBSD 7.3) which loads from the ISO on boot. This winds up being the root partition. As a datapoint the same die roll happens on FreeBSD 7.3 although the chance of working seems to be greater. If you'd like a copy of the ISO to see this for yourself I can make it available. I'm guessing it will also crash for you in this way modulo hardware issues. -- Dave Hayes - Consultant - Altadena CA, USA - d...@jetcafe.org >>> The opinions expressed above are entirely my own <<< The treasure house within you contains everything, and you are free to use it.

Dell T710 with Xeon x5660 Kernel Panics - Fixed under 8.1-STABLE
BTW, just passing on that my Dell T710 which would Kernel panic under 8.1-RELEASE randomly between 10 minutes-2 days, no longer does this under 8.1-STABLE. I was running it with 2 of the new Intel 6 core Xeon's - X5660 Under 8.1.-RELEASE FreeBSD didn't recognize the processor, and I guess that's causing APIC table load issues? I had tried 2 reinstalls, and building a custom kernel, and always the same issue. My CPU is detected properly under STABLE, and looks to be rock solid - Except for a small ZFS bug that may report a bit later when I have time for screen shots. I still have the old HD with 8.1 STABLE on it, and can load it up if anyone needed me to find out exactly the difference.
