Priority: medium Bug ID: 60439 Assignee: dri-devel@lists.freedesktop.org Summary: Suspend/resume broken for cayman since kernel >=3.7.0 (maybe rc too) Severity: major Classification: Unclassified OS: Linux (All) Reporter: h.judt@gmx.at Hardware: x86-64 (AMD64) Status: NEW Version: XOrg CVS Component: DRM/Radeon Product: DRI
In all kernels newer than 3.6.x, suspend & resume is broken for cayman. It works fine in 3.6.11 and lower. Last tested release where issue is reproducible is 3.8.0-rc6.
Suspend seems to work ok as nothing hangs, but on resume the console appears with a blinking cursor at the top left corner, then after some seconds the video signal seems to be turned off and the monitor goes into powersave mode. SSH doesn't work, machine seems frozen. Hello, reset button!
I can bisect but would appreciate it if you could tell me which commits count as possible bad candidates.
(Also I noticed that in 3.8.0-rc6, the compiz-0.8 splash screen is garbled, which it is not in 3.7.x and 3.6.x, but that's a different issue.)
