Red Hat Bugzilla – Bug 447924
Intel Stoakley on board Ethernet devices do not start up with latest RT Kernels
Last modified: 2010-02-16 08:05:05 EST
Description of problem:Intel Stoakley 2 socket Quad Core with 2 onboard IOAT
network ports do not work using igb drivers. E1000 drivers and 10g drivers work
Version-Release number of selected component (if applicable): 188.8.131.52-57
How reproducible: does not work at all
Steps to Reproduce:
1. boot with kernels 184.108.40.206-56 or 220.127.116.11-57
2. kernel does not recognize the igb driver for eth0 or eth1
On board 1gb network cards do not come up. In /var/log/messages,
With rhel 5.2 we see this
May 19 05:36:22 perf6 kernel: e1000: eth0: e1000_probe: Intel(R) PRO/1000
May 19 05:36:22 perf6 kernel: igb 0000:0b:00.0: eth0: (PCIe:2.5Gb/s:Width x4)
May 19 05:36:22 perf6 kernel: igb 0000:0b:00.0: eth0: PBA No: ffffff-0ff
With RT kernel
May 20 04:27:10 localhost kernel: e1000: eth0: e1000_probe: Intel(R) PRO/1000
then nothing more
Expected results: eth devices to come up

where can we get access to stoakley h/w?
You need to coordinate with Sanjay Rao (firstname.lastname@example.org) of John
Shakshober (email@example.com) for access to the machines. They are currently
using it. We moved the public network off the igb NICS's so the name of the
machine is dhcp47-68.lab.bos.redhat.com
is this still an issue with the latest 18.104.22.168-132 kernel?
The igb driver was introduced on MRG 22.214.171.124-89, so it was not present on 126.96.36.199-57, the kernel used for the first test. The ixgb and ixgbe drivers were added later on and updated on kernel 188.8.131.52-138.
Our current errata kernel is 184.108.40.206-146.
I will close this bug. Please feel free to reopen it case you have any similar issue with newer kernels.
