>Description:
This machine has been crashing since I upgraded to 4.0-STABLE via 4.0-RELEASE.
Output kgdb :
(kgdb) where
#0 0xc013f108 in boot ()
#1 0xc013f48c in poweroff_wait ()
#2 0xc0260881 in trap_fatal ()

Cannot access memory at address 0xbfbff7f8.
Panic reads:
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0xc14ebff0
fault code = supervisor write, page not present
instruction pointer = 0x8:0xc025e748
stack pointer = 0x10:0xc6268ed4
frame pointer = 0x10:0xc6268ee4

processor eflags = interrupt enabled, resume, IOPL = 0
current process = 31182 (cc1)
interrupt mask = net tty bio cam
trap number = 12
panic: page fault
( note that all panics aren't consistent , sometimes the machine simply locks up )
I assumed this was a hardware fault, replaced memory and installed clean on another HD, same problems.
Installed 2.2.7 and it worked fine.
>How-To-Repeat:
attempt to make buildworld does it everytime.
Also crashs when running scheduled locate.updatedb , and to test I ran a
backup on my /usr and it crashed. SEEMS related to system load.
>Fix:
Don't know. Power Management ? My hardware is the same as it was when I was running 3.4-STABLE,
and it was , STABLE, sigh.
