We just saw this kernel warning on 2.6.34.1 + a few patches from the pending stable queue, plus our own hacks (though none to igb).

We were running a modified version of pktgen traffic and at the same time bounced the port.

This warning didn't seem to cause any real problems.

Please let us know if you would like any additional information.

RE: 2.6.34.1: kernel warning at igb_main.c:2080

In reply to Ben Greear

Hello Ben,

I'm not exactly sure why this happened and there's not a lot of info from the kernel, unfortunately. I've looked at the location in the code and it doesn't give me much more. Let me know if it is happening regularly and if you have steps to reliably reproduce it and we can look at it further.

We do appreciate the report.

Thanks,

Carolyn

Hello Ben,
I'm not exactly sure why this happened and there's not a lot
of info from the kernel, unfortunately. I've looked at the location in the code and it doesn't give me much more. Let me know if it is happening regularly and if you have steps to reliably reproduce it and we can look at it further.

We do appreciate the report.

Thanks for looking. We haven't noticed this again.
If we figure out how to reproduce it reliably, I'll let you know.
Thanks,
Ben
