Comment 6 for bug 615053

How do I check the firmware version?

I have this on all my machines, all running different version of Ubuntu
( all are similar hardware).

It only occurs when the card is under 100% utilization for several seconds.
I have recently lowered the chance of this happening by bonding the
multiple interfaces.
Now it only happens rarely.

I also try to limit the bandwidth usage through application setup.
