You should be able to bring up the network again by doing 'service 
network restart' rather than rebooting the machine.

Supposedly, loading the bnx2 module with disable_msi=1 resolves this 

There is a version of the netxtreme driver available that is newer than 
the one provided by RHEL/CentOS.  You can get this from Dell's site.  In 
my experience, using this driver resolves the problem.
