Attached is a patch to fix the soft lockup problem when removing the 
netconsole module.

It looks different than the original patch I posted because the context 
had to change to maintain 80 column code.  For reference the original 
e-mail + patch was "[BUG] 2.6.21 hang in 
cancel_rearming_delayed_workqueue()" sent on 5/25/07.
