I would like to test a patch!
My guess is that it is related to the driver more than the firmware. However, I've never heard of this problem before. If you think it is related to the driver/firmware then you might want to contact the Intel developers on the e1000 mailing list. _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
