>Description:
I've been experiencing random panics with different programs. This one, recently was bash. I'm using multi-CPU machines and this has been happening on them lately.
Fatal trap 12: page fault while in kernel mode
mp_lock = 00000002; cpuid = 0; lapic.id = 00000000
fault virtual address = 0x0
fault code = supervisor write, page not present
instruction pointer = 0x8:0xc03876b3
stack pointer = 0x10:0xff390bdc
frame pointer = 0x10:0xff390c08
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 = 342 (bash)
interrupt mask = none <- SMP: XXX
trap number = 12
panic: page fault
mp_lock = 00000002; cpuid = 0; lapic.id = 00000000
boot() called on cpu#0
>How-To-Repeat:
Unknown.
>Fix:
Deinstall 4.x and down-install to freebsd 3.2 :-)
