I can't seem to get my Voyager to shutdown -p.  Not a big problem, but 
I was wondering why this didn't work.  On a (possibly) related note, 
does anyone know what the SUNW,pmc device is?
SUNW,pmc at sbus0 slot 4 offset 0x1300000 level 2 (ipl 3) not configured

Using 1.6ZC (as of yesterday).

syncing disks... done
unmounting / (/dev/sd0a)...
