x86 only: 3Com EtherLink 3C509B Does Not Generate Interrupts (4153488)

3Com EtherLink III 3C905B cards in a Compaq ProLiant 6500 can fail to generate interrupts. The card sends packets but does not receive them.

Workaround: There is no known workaround for this problem. However, because some slots appear to have this problem occur more frequently than other slots, moving the card to another PCI slot might help. Also, successive reboots of the system have succeeded in getting the card out of this state.
