Running FOG 0.32 on Ubuntu 11.04
I am experiencing the same problem, even without using Dell Vostro clients.
Receiving the
NOHZ: local_softirq_pending 08
error repeatedly regardless of the machine type.
Our short term solution to this problem was replacing all of the gigabit switches on the network with 10/100 switching. Now everything works, but slowly. I would be interested to know why this worked.
