Created attachment 115031 --> https://bugzilla.kernel.org/attachment.cgi?id=115031&action=edit dmesg output with drm.debug=0x0e
Reported at openSUSE bugzilla https://bugzilla.novell.com/show_bug.cgi?id=841822
The original bug report:
Toshiba P775D-S7230 AMD APU A4, resume from suspend leaves screen "black".
WHen I compiled and installed the proprietary AMD driver (13.8B2), it works fine. Same behavior on 12.3 as well.
Reproducible: Always
Steps to Reproduce: 1. Make sure AMD FOSS driver is loaded 2. Suspend (to ram or disk) 3. Resume 4. Screen is blank, machine is "resumed" Actual Results: The machine appears to be in a working state, but the screen is black
Expected Results: Full function resume from suspend with video
Compiling and installing the AMD proprietary driver (13.8B2) works.

The problem is seen without X, too.
Reproduced on (openSUSE) 12.3 means that kernel 3.7 had already the problem. openSUSE 13.1 uses 3.11.x kernel, and the reporter tested 3.12 kernel, too.
The full dmesg with drm.debug=0x0e after S4 resume is attached.
