Sorry,I forgot it. Here it is for the last patch: Signed-off-by: Michael S.

It is also relatively straight-forward code so I would suspect a driver problem first of all. Unfortunately once the overrun happends I can not bring the interface down nor unload the ip over ib module (both commands hang) so I have to reboot. This is slowing me down considerably. Do you have an idea why is that, and how to fix this problem?
