I have been running the same kernel with the same stack for a few days now (and at least 5 suspend-resume cycles) with i915.powersave=0 and it works fine. So the issue is caused by powersave features. Issue is still present on Linux 2.6.34-rc2-00288-gb72c409 x11-libs/libdrm-2.4.19 media-libs/mesa-7.8 x11-base/xorg-server-1.7.6 x11-drivers/xf86-video-intel-2.10.0-r1 Can you try the drm-intel-next branch of git://git.kernel.org/pub/scm/linux/kernel/git/anholt/drm-intel? It disables framebuffer compression on 945 chips, where hardware bugs generally keep it from working right.

Hehe.. well it gets rid of the flickring and corruption issues, but sometimes when resuming from suspend the screen still stays black. Yeah, we have another bug open for that issue. :p Sorry about that, but thanks for confirming this one. |
