Bug ID: 65141 Summary: Blank screen after resume with radeon driver Product: Drivers Version: 2.5 Kernel Version: 3.7,3.11,3.12 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: tiwai@suse.de Regression: No
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.

--- Comment #1 from Dennis Jansen dennis.jansen@web.de --- Try the kernel parameters: nomodeset vga=0 (for X, load radeon with modeset=1, e.g. via modprobe.d options)
With my system, at least resume from hibernation then works with an active display. Did not find a fix to suspend to ram, though.
(Also running AMD A4 here)

--- Comment #3 from Andreas Wiener aw@corti.de --- Hi, I am experiencing the same issue with an AMD A6 CPU. I tried with 3.13 and now 3.14 kernel but the problem persists. I am also running opensuse 13.1.
I attached my dmesg before and after with drm.debug=0x0e. Please let me know if I can help with additional information.
