Comment 32 for bug 573259

Have/had the same problem with wife's HP. Ended up warrantying the box the first time it happened as it killed it in 10.4 and Win 7. Second time, I noticed it happened when I tried to configure power saving in 10.4. When I undid the power saving, it came back. This last time there had been no power saving changes done, but there were updates applied. Since she is good about applying them when they are available, they just got done. I did not check the logs to see what was patched though. Same thing happened. Dead NIC in both kubuntu and windows through reboots and power cycles (windows is hardly ever used).

Unplugging the power supply on the motherboard for a few minutes brought it back to life.
