Actually, that's not the fix. I thought this 'fixed' it too, but you'll 
have a broken network in a few hours.

The fix is to disable PCI-E ASPM. In the BIOS there is an option for 
Active State Power Management, and you need to set it to disabled.

There is a hardware flaw in the 82574L that prevents ASPM from working.
