I just rebooted with a kernel built yesterday, supped at about 3am our
time (18:30 UTC on Wednesday, 3 September).  It doesn't make it
through the boot.  I was also unable to get a dump: after entering
'pa' to ddb, it just rebooted without dumping.  Possibly it hadn't got
round to mounting the swap partition.

Anyway, the process that died was an 'rm'.  Here's the stack trace.

vgonel+0x156
vrecycle+0x19
ufs_inactive+0x16b
vputrele+0xf9

vm_object_deallocate+0x17f

Registers:

cs	0x8
ds	0x10
es	0x10
ss	0x10
eax	0x0
ecx	0xf0726900
edx	0x0
ebx	0xf0726900
esp	0xf4ba7d78
ebp	0xf4ba7d84
esi	0xf0726900
edi	0xf0726900
efl	0x10246

If I have to, I can reboot and try things out.
