root at filer:~# dumpadm
      Dump content: kernel pages
       Dump device: /dev/zvol/dsk/rpool/dump (dedicated)
Savecore directory: /var/crash/filer
  Savecore enabled: yes

I walked over to the console to see the machine rebooting.  gdm is
disabled on this box.

One point of possible interest is that the target fs is on a zpool
with 'compression=6' enabled - that is, gzip level 6 compression.

The machine has 4gb ram, which means the 2gb dump zvol should be big
enough, IIRC.
