After much toing and froing on LKML, netdev and the e1000 mailing lists over the past few months we've determined that the 82574L needs to have both ASPM L0s and L1 disabled or else it's likely to lock up. This little series does just that, also cleaning up some now-unnecessary code that disables L1 on the 82573 and 82574 if the MTU is greater than 1500 bytes.
Please note I haven't as-yet tested this code at all, but I do know that disabling ASPM L1 on these NICs (using setpci) fixes the hangs that I have been seeing on my Supermicro servers with X9SCL-F boards. I hope to get the chance to install an updated kernel on my two afftected servers later this week.
