>Description:
I just had my second kernel crash shortly after running
"shutdown -r now". Following is the output from the kernel
debugger and a backtrace that i've written down and typed in:
vm_fault(f86ad900, 0, 1, 0) -> 1
kernel: page fault trap, code = 0
stopped at _ffs_sync+0x17: movl 0xc(%edi),%eax
_ffs_sync(f8665000, 2, f8668d80, f86ada00) at _ffs_sync+0x17
_sync(f86ada00, f7bfff94, f7bfff8c, 0, f7bfdf80) at _sync+0x48
_syscall() at _syscall+0x174
--- syscall (number 36) ---
0x1003a800:
The one and only ffs filesystem that was mounted is my combined
root&usr filesystem (4.4BSD ffs).
