Red Hat Bugzilla – Bug 484376
netdump is broken on igb and ixgbe devices in recent update
Last modified: 2014-06-29 19:01:05 EDT
Because of the use of extra netdevs created for MSI-X/NAPI support these devices cannot properly netdump.
I already have patches available in my test kernels here:
More testing is needed, but I feel good about these so far.

Please test them and report back your results. Without immediate

I tested the kernel 2.6.9-87ELsmp and the behavior mentioned in "Issue 280863 - RHEL-4.8-Beta1: ixgbe panics when the device is opened" is not seen. The driver doesn't panic when the device is opened.
