Things that you really ought to tell us: - CPU? - model or motherboard identifier? - have you tried disabling low C states in BIOS? - you say it's been reported across major kernel releases -- what bug numbers? - are there any log entries written before it freezes? - can you avoid it by not unplugging/replugging the ethernet cable? - what ethernet NIC is in use? - have you run htop or another means to disable power saving on the NIC? ...and probably a dozen other things, but start there. -dsr-
