How reproducible:
1. Depends on your luck.


Steps to Reproduce:
It occured after reboot. But i have 3 the same machines with 3 the same ethernet controllers, and another 2 works (still).
I copied eeprom from other machines, but i have no idea now to restore it to broken cards, because eth0 and eth1 are missing, so ethtool -E doesn't works

  
Actual results:
No eth0 and eth1 interfaces. Only lo in "ifconfig -a" output.


Expected results:
Have eth0 and eth1 and network connectivity.
