Unpatched without SMP.  
Running the packet generator causes the packet generator process to 
hang.  It doesn't appear to complete normally.  The netdev watchdog 
complains of a timeout.  Killing the packet generator works.  However, 
the network device becomes unresponsive -- requiring a reboot.  Under 
normal load, this kernel seems to work.

Patched with SMP.
Running the packet generator causes the packet generator to complete, 
but the netdev watchdog still complains of a timeout.  Sure enough, the 
network device becomes unresponsive -- requiring a reboot.  This system, 
during normal load, is completely unusable.  The first network request 
seems to lock the network device.
