we have had many problems with the Intel NICs that come embedded on the 
supermicro twin boards when paired with nortel switches. Setting the MTU 
to anything other than 1500 results in cards coming up in a strange 
state 50% of the time. Also, PXE has been a problem with certain 
versions of the driver not to mention the extra confusion over e1000 and 

These report themselves as:
