Description Andy Gospodarek 2009-02-06 14:52:41 UTC

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:

http://people.redhat.com/agospoda/#rhel4

More testing is needed, but I feel good about these so far.

Comment 1 RHEL Program Management 2009-02-06 14:59:27 UTC

This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release.  Product Management has requested
further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products.  This request is not yet committed for inclusion in an Update
release.

Comment 2 Andy Gospodarek 2009-02-12 12:40:30 UTC

My test kernels have been updated to include a patch for this bugzilla.

http://people.redhat.com/agospoda/#rhel4

Please test them and report back your results.  Without immediate
feedback there is a good chance this or any other fix for this driver
will not be included in the upcoming update.

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.
