Ah yes, that was what I was going to try next, if I didn't hear back
from anyone :)
I'll let you know if that changes anything. This box has been hanging
for a little while now, on an inconsistent basis -- this was just the

no console, serial or physical, no SysRq, nothing. It's all rather odd.
Will keep you posted.

Nish
