kernel BUG domU, rev 7701

[Andrew Theurer]

Anyone seen something like this? This doesn't happen all the time, so 
it's hard to reproduce consistently. Actually, thinking about this, it 
seems to happen when I am scp'ing something from dom0 to the domU. This 
is on x86_32, 2 x Xeon, HT disbaled, SMP domU:
