Description Felix Homann 2014-05-14 08:42:32 UTC

My sytem won't wake up (properly) after suspend when using a Radeon R7 260x: The screen stays black and the system cannot be reached over ssh. Using the onboard Intel graphics adapter the system will wake up properly with the same kernel.

This has not been a problem with 3.13.x kernels. I have not tested with 3.14 kernels.

I am using the MESA driver, the BONAIRE_mc2.bin firmware is present. Overall performance of the driver is great.


The kernel I'm using is commit 14186fea0cb06bc43181ce239efe0df6f1af260a from Linus' tree.

Here's the output of ver_linux:

Sounds like a duplicate of https://bugzilla.kernel.org/show_bug.cgi?id=75651

Comment 2 Felix Homann 2014-05-14 09:37:16 UTC

The proposed patch https://bugzilla.kernel.org/attachment.cgi?id=135881 doesn't fix the issue on my machine.

Comment 3 Christian König 2014-05-14 09:42:51 UTC

Then please bisect what commit broke it for you.

Comment 4 Felix Homann 2014-05-14 09:55:59 UTC

I'll do (*). But bisecting will not be that easy as the R7 260x is mostly broken on 3.14.x anyway, see https://bugzilla.redhat.com/show_bug.cgi?id=1094153 and the corresponding report on freedesktop.org. The bisect result might get wrong due to the overall 3.14.x issues.


(*) I probably won't find any time for a bisect session before May 26.

Comment 5 Felix Homann 2014-05-14 10:07:37 UTC

OK, 3.14.x kernels will resume fine if I suspend before the screen freezes.
