I was suggesting to someone that they enable crash dumps on their server 
but they have everything on an IDE raid partition.
--------------------
Fatal trap 12: page fault while in kernel mode
fault virtual address   = 0xbed557c5
fault code              = supervisor read, page not present
instruction pointer     = 0x8:0xc027c38d
stack pointer           = 0x10:0xdea01ecc
frame pointer           = 0x10:0xdea01ef4
code segment            = base 0x0, limit 0xfffff, type 0x1b
                         = DPL 0, pres 1, def32 1, gran 1
processor eflags        = interrupt enabled, resume, IOPL = 0
current process         = 5 (syncer)
interrupt mask          = none
trap number             = 12
panic: page fault

syncing disks... 8
done
Uptime: 1d0h9m53s

dumping to dev #ar/0x20001, offset 1279168
dump failed, reason: device doesn't support a dump routine
Automatic reboot in 15 seconds - press a key on the console to abort
---------------------------
The error message seems to imply crash dumps are not supported on the ar 
device? Apart from installing a spare drive, I guess there are no other 
option ?
