I tried cgminer on a couple of my boxes last night and woke up to find 3/4 GPU marked as DEAD on one and 2/4 DEAD on another. Trying to restart the DEAD GPU doesnt seem to do anything on either machine (restarting the ones still running did seem to restart them OK). Both boxes have been running for weeks using poclbm without errors. Running the 1.5.3 binary on Ubuntu (3xHD5870 and HD6310).

Anyone else seeing problems with DEAD GPU that won't recover unless cgminer is restarted?
