I was thinking power failure, too.
However, the original 3-card rig was drawing 460Watts at the wall thru a Corsair 750W rated PSU so I think
I had good margin.
Now the card is sitting alone in a spare rig to see if it runs stably overnight.
Thanks again for tipping about the caps and possible power issue.

I'm happy for you

The symptoms are of a power failure, but perhaps with ubuntu kernel gives a similar failure.
happy mining Grin

Thanks for the tip.
The card was not broken.
I reverted back to kernel version 3.2.0-72 from 3.2.0-74 and reinstalled the stock driver.
And voila, the card is now working again and sgminer is hashing away.
I have had instabilities with kernel version 3.2.0-74 and higher in another rig, and this
strengthens my belief that something was broken in kernel version 3.2.0-74 and higher.

Damaged card.
Remove the cooling system and looks electrolytic capacitors(16v). look If anyone is inclined or has combustion residues at its base. Also look at the R392-393 resistors or others that are around the power inputs . If it is difficult for you, take it to an electronic repairs. It is a low cost repair.

Your card works now because r392-393 resistors are not completely burned.
I had the same problem.

280x is under current manufacturer's warranty. send service technical assistance

This card was sitting in a rig with 2 other R9 280X cards running sgminer 5 under Ubuntu 12.04 when suddenly the
miner hung and top command revealed Xorg at 99% cpu. Driver problem, I thought and rebooted the rig.
But Ubuntu refused to boot up. I took the card out and inserted into another rig. This time the machine booted
but refused to start X. Stock driver under 12.04.
I took the card out and into a Windows 7 machine. This machine booted no problem and I was able to start sgminer.
Now, however, I am not able to adjust core or memory frequency thru sgminer, only fan % is adjustable.
I am able to adjust these parms from Sapphire Trixx, however.
Anyone has a clue what is going down here?
