--- Comment #94 from Alex Deucher agd5f@yahoo.com --- (In reply to comment #92)
The bug is still not fixed. Been using Radeon 3650 with dpm, and now running rc5.
Everything went well until I had a reboot due to a NOD32 install. That time I encountered the white screen of death once again.
Can I gather any more debug info somehow Alex? (I use a total non-debug kernel that I compiled but I can prepare one full debug version if you would like.)
Can you try disabling additional dpm features as per previoous comments? e.g,

See if disabling any additional features helps stability on your system.
ps.: I'm not too lucky with this DPM thing. The old card dies randomly (WSOD), and the new one is not supported (SI).
SI cards are supported just fine, including dpm.
