Looks like you're hitting an old bug where there is a race between something
running in the background continuously hitting ethtool ioctls and the driver's
watchdog.

Can you identify which program is doing the ethtool command? That would help.

Please re-test with the latest git tree  - I believe that we just recently fixed
this bug, and I'm almost sure that your kernel does not have that fix.

Cheers,

Auke
