Mainboard DQ77MK: onboard NIC fails

Community Manager

I own a DQ77MK mainboard. It's equipped with two gigabit NICS: an 82579LM and an 82574L. One NIC is connected to a production segment, one to a management segment. The 82574L fails frequently, after somewhere in between half a day and a week. A check right after connectivity is lost shows that - according to Windows - the NIC is disconnected from the network. this is NOT the case: NIC LEDs are still active and the link on the switch is still up. After a couple of seconds the NIC completely disappears from the Windows network control panel. If I swap the network cables and IPs the problem reoccurs on the other network so it seems to be 82574L related.

Any clues about what's going on? Hardware / firmware / driver bugs? Something else? Thanks!

Hmmm, news about a 'packet of death' for the 82574L and talks about an EEPROM update to fix this @ Not Just AstLinux Stuff: Packets of Death. This might be related...
