Priority: medium Bug ID: 72710 Assignee: dri-devel@lists.freedesktop.org Summary: rv635: resume fails Severity: normal Classification: Unclassified OS: Linux (All) Reporter: h.judt@gmx.at Hardware: x86-64 (AMD64) Status: NEW Version: XOrg CVS Component: DRM/Radeon Product: DRI

With kernel-3.12.0, the system fails to resume from suspend/hibernate. - It always fails with radeon.dpm=1. - It fails most times with radeon.dpm=0. Usually it works on the first try but fails on the second or third, but sometimes even the first try is unsuccessful.
The screen goes black before it starts reading the pageset2 data, the numlock/scrolllock leds start blinking indicating a kernel panic. A hard reset is required. There are no weird messages in dmesg (no_console_suspend=1).
As for the kernel version, I think the problems started around 3.7.0 or maybe one of its release candidates. Since there have been so many changes and quite a few problems with those versions, I'm not sure how to bisect this. The last reliable version that I used was 3.6.2. I have also pulled the drm-next-3.13 patches into 3.12, but it didn't help.
Apart from the failure to resume, the driver works fine (even with dpm enabled), I have no lockups nor crashes.

I have attached the video bios rom, maybe it is of use?
