Description of problem: We got a Celestica A8440 server with an amd8111 network interface, and this interface generate numerous `Driver bug! interrupt while in poll' lines when used. eth2: AMD-8111e Driver Version: 3.0.5 eth2: [ Rev 3 ] PCI 10/100BaseT Ethernet xx:xx:xx:xx:xx:xx Version-Release number of selected component (if applicable): kernel-smp-2.6.9-34.0.1.EL How reproducible: Always. Steps to Reproduce: 1. Set all network interfaces (2 tg3, and 1 amd8111e). 2. Generate some traffic on amd8111e interface (some big ftp transfert). 3. Watch `Driver bug!' messages on console. Actual results: `Driver bug! interrupt while in poll' in console with some traffic on the interface. Expected results: No messages on console. Additional info: This issue seems to have been resolved in vanilla 2.6.12-rc6 kernel: Liu Tao: drivers/net/amd8111e.c: fix NAPI interrupt in poll

I just installed the `kernel-smp-2.6.9-40.1.EL.jwltest.149.x86_64.rpm', and does not see the `Driver bug!' messages anymore. This is with the same ftp download that triggered the problem before. Looks promising ...
