--- Comment #11 from Harald Judt h.judt@gmx.at 2011-07-30 04:27:57 PDT --- Ok, another update, including some positive results:
Compiled updated kernel based on 3.0 final: http://git.kernel.org/?p=linux/kernel/git/nigelc/tuxonice-head.git;a=summary merged branch git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6.git drm-core-next @5a96a899bbdee86024ab9ea6d02b9e242faacbed
* Hibernation & resume still does not work correctly, leaving the power profiles unfunctional
* Suspend & resume now works reliably and can be performed successfully multiple times after hibernation & resume, fixing the power profile issue caused by resume from hibernation
Strange. The driver doesn't differentiate between the two.
Do you think it's a bug in the general hibernation / resume code, meaning I should ask somewhere else? What speaks against this is that the same config works on a laptop (ATI Mobility Radeon HD 3400) where there are no such issues, hence I concluded that this *might* be specific to HD6950/Cayman.
