The network seems okay.

The SSH session doesn't close. It just sits there, initiating another
SSH just sits there as well, it doesn't time out or anything.

I'll compile a debug kernel tonight, and I'll put in the other disk
that "should" lock up, tomorrow and copy a few gigs across.

The first time it locked up was when i was copying
cp -va
from one disk (degraded mirrror) to the other disk (degraded mirror +
gjournal). Copied around 40GB until it locked up. It did it 3 times
before i manage to copy everything over. Re-syncing of the mirror
works fine.

Should i use
options KDB
options DDB
options WITNESS
