(12:13:24 PM) bwh: Seems like a bug in the forcedeth driver (or hardware)
(12:15:09 PM) bwh: It apparently received a packet 1664 bytes long, but it should be limiting to 1518 bytes by default
(01:04:08 PM) bwh: That oops message shows an 'M' taint flag which means there has been a machine check exception, which normally indicates a hardware fault of some sort
