The kernel panic below is generated at boot, and is reproduceable as many times as you want to do it. A few details on the hardware, the machine is a couple of years old, but never displayed any real instability. My only suspect hardware is the hard drive itself, and possibly ram, however seatools and memtest clear them both with flying colors, for what that's worth. The machine is an Athlon XP1900+, and I'm still running GENERIC (I usually compile something custom after a machine has been up and going a while, but this was only installed this past week) and the machine is under light load at best, running natd, apache, mysql and postfix for my home network. One thing I will point out is that the power went out yesterday on this machine, and while the UPS's normally keep everything up, apparently the power was out for more than 30 minutes because all of my machine's rebooted. When this one came back up, it had hosed /var/log, but a good fsck cleared that up. Later it quit working, and I got a brief look at a panic before it rebooted - I know nothing about the first panic other than it was a kernel panic. When it rebooted it came back to where it would mount / and stopped, with the infamous mountroot> prompt. I politely advised it that it needed to look ufs:ad1s1a and got the following panic - forgive any formating errors on my part - I assure you the information I copied off the screen is correct. Warning: / was not properly dismounted Fatal Trap 12: page fault while in kernel mode cpuid = 0, apic id = 00 fault virtual address = 0x188 fault code = supervisor read, page not present instruction pointer = 0x20 : 0xc0747d14 stack pointer = 0x28 : 0xe3391aa0 frame pointer = 0x28 : 0xe3391ab8 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor flags = interupt enabled, resume, IOPL = 0 current process = 1 (swapper) trap number = 12 panic: page fault cpuid = 0 uptime: 42s All of this panic can be reproduced character for character (except the uptime, unless you try real hard) time and time again. Any pointers on what might be wrong here? Thanks in advance. Drew
