(moving the discussion back to the list) Hi, I am sorry, I didn't receive your patch as we discussed in private and ended up writing one patch myself which essentially does the same thing. The patch is available at: https://bugzilla.redhat.com/show_bug.cgi?id=746272#c13 It schedules a workqueue

Re: [E1000-devel] 82571EB: Detected Hardware Unit Hang

Hi, Flavio, Jesse I have send out the patch, which I hope can do some help. Because this is my first time to send a patch, I am sorry if I have done some silly thing. And please tell me if there are some problem about it. Thanks & Best regards, Michael Wang
