Hi, I'm getting the same panic repeatedly on -STABLE. The time length between panic's varies between about half an hour and several days. It doesn't appear to be related to system load. The machine is used as a Desktop - with a few things running. I put some load on the machine (average of around 40.5 or so and lots of swapping) for an hour. The machine was fine. That also makes me doubtful that this hardware related. I have been unable to determine any particular pattern for the occurance of these panics. There doesn't seem to be a trigger that I've noticed. => Fatal trap 12: page fault while in kernel mode fault virtual address = 0xc0bf9953 fault code = supervisor write, page not present instruction pointer = 0x8:0xc02842ff stack pointer = 0x10:0xcca0ff38 frame pointer = 0x10:0xcca0ff44 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 3 current process = 67995 (XFree86) interrupt mask = net trap number = 12 panic: page fault <= => (gdb) bt #0 0xc0131fa2 in dumpsys () #1 0xc0131d6c in boot () #2 0xc01321b9 in panic () #3 0xc01dafac in trap_fatal () #4 0xc01dac41 in trap_pfault () #5 0xc01da793 in trap () #6 0xc02842ff in ??

I shall try and find out the problem, but my skills are still immature. I can provide dmesg and other information on request.
