We were using the 3com 905b cards on 2 16 node clusters. Our application
keeps the network pegged most of the time. We were getting network
hangs about once every two weeks running RH6.1. We moved to RH6.2
and switched to the 3c90x driver and problem happened about once per
day. We have since changed out the 3com cards for the EtherExpress PRO 
10/100 and have not seen the problem but we only have about 3 weeks of
runtime on this configuration.
