I will probably push this patch upstream since it should resolve your issue.
I would like to test it out first, but don't have access to any hardware today.
Would a test-build be helpful or would you like to try this patch yourself?
If you would like a test-build let me know what ARCH you would like and I can
put one together.
The machine that has the problem is a production server, please, give me two
or three days to schedule a reboot. Thanks.
I posted the patch from Comment #1 to netdev since it seemed fine to me.
