fatal trap 12

[Mitja]

Hi!

My system:  FreeBSD 7.0-RELEASE-p4 #1

My computer keeps hanging up. As a desktop I use KDE and I have Power 
Management on. Once, twice or everyday I found my computer "frozen" in the 
morning. There are no logs. Last two weeks  I logoff from X-server and live 
computer in console. Ten days was okay and problem start again but now I have 
something:

Fatal trap 12: page fault while in kernel mode
cpuid=0, apic=00
fault virtual address = 0x10
default code: supervisor write, page not present\
instruction pointer:0x20:0xc0466196
stack pointer = 0x28:0xe53184a8
frame pointer= 0x28:0xe5318734
code segment = base0x0, limit 0xfffff,=DPL 0, press 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 33(usb4)
trap number = 12
panic page fault
cpuid = 0
uptime: 12h58m30s

Thanks in advance...
