This happened on archlinux after upgrade to kernel version 3.6.2.

The following warning is printed several times in logs:

Comment 1 vivenzio 2012-10-18 04:34:03 UTC

Forgot to mention that hardware has Intel GM45 chipset.

Comment 2 Daniel Vetter 2012-10-18 07:08:43 UTC

Can you please test 3.7-rc1? That contains a completely rewritten modeset code, which turned up an issue (plus fix ofc) which might apply for you. If you test 3.7-rc1 please add drm.debug=0xe to your kernel bootline and attach the complete dmesg after having reproduced the issue (i.e. after resuming).

dmesg after poweron (not resume) with kernel 3.7rc1 and drm.debug=0xe

The WARNING() also shows up at boot time, when I poweron.

dmesg output after resume from hibernate with kernel 3.7rc1 and drm.debug=0xe

The flickering artefacts are not visible anymore, however the WARNING() from intel_disable_pipe() is still there.
Attached is the dmesg output after resume from hibernate with kernel 3.7rc1 and drm.debug=0xe on kernel command line.

Daniel, I think this is the pipe<->plane sanitizer, right?

Comment 8 Daniel Vetter 2012-10-22 17:24:42 UTC

Yep, please upgrade your kernel to 3.7-rc2, this is fixed in
