Hi, I just tried 3.15-rc6. I encountered a pretty nasty problem, which is after suspending to RAM the system doesn't wake up properly. v3.14 is fine. On wakeup all seems fine, i.e. hd starts to spin an USB-stuff wakes up. But all I get from the graphics card is a white screen slowly filling with random colored pixels. I had to hard reset the system.

I attached the kernel log, the X-servers log, lspci-output and my kernel config.

Regards Malte

I have seen a bit of a screen distortion at the bottom of LCD on Radeon after a wakeup. I tried to re-run with drm.debug=0x0e, however once I did it - the problem has disappeared, and I have not been able to duplicate it again. So just watching for now. OTOH I have seen (only one time) a black screen after wakeup on Nvidia. So maybe some timing is now exposed in PM / DRM...

I pulled git://people.freedesktop.org/~deathsimple/linux drm-fixes-3.15 from http://article.gmane.org/gmane.comp.video.dri.devel/106114 and my problem is gone ...

Also fixed in v3.15-rc7.
