You won't happen to be getting a "Fatal trap 12" when you reboot?
root[0]: shutdown -r now
gives
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x8
fault code = supervisor read, page not present
instruction pointer = 0x8:0xf013fd15
stack pointer = 0x10:0xefbffe5c
frame pointer = 0x10:0xefbffe60
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def 32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL=0
current process = 1862 (reboot)
interrupt mask =
kernel: type 12 trap, code = 0
stopped at _spec_strategy+0x15: movl 0x8(%eax), %eax
The mounted filesystems are not unmounted before the trap and I get
dropped into the debugger. A hard reset shows all filesystems have
some damage.
Kernel and make world from sources circa 970312, 1000 PST.
