I recently swapped out a motherboard in a FreeBSD server for a new Intel
Pentium 4 motherboard/processor to gain speed.
Since that time, this machine has been randomly panicing such as:
Fatal trap 12: page fault while in kernel mode
mp_lock = 00000003; cpuid = 0; lapic.id = 00000000
fault virtual address = 0x36
fault code = supervisor write, page not present
instruction pointer = 0x8:0xc01f60fe
stack pointer = 0x10:0xf25cdab8
frame pointer = 0x10:0xf25cdb58
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 454 (perl)
interrupt mask = net bio cam <- SMP: XXX
trap number = 12
panic: page fault
mp_lock = 00000003; cpuid = 0; lapic.id = 00000000
boot() called on cpu#0
>From my symbol table, this particular panic appears to have occured in
vm_fault:
c01f5fcc T vm_fault
c01f6b1c T vm_fault_wire
This appears to be pretty consistent (the instruction pointer). It used
to panic both where I mentioned above and also in pmap.c. Since I did the
last cvsup and kernel rebuild, I haven't seen one from the pmap area.
Any ideas?
