With recent drm-intel-experimental kernels taken from Ubuntu, e.g.
http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-experimental/2012-09-29-quantal/
commit 17dc92574b696ba07512f7e6cfb7941a6f873f45
and with a week old kernels as well, there are following messages in dmesg
(similar to Bug 49838 and Bug 51265 )

With G33, I have:
plane A assertion failure, should be off on pipe A but is still active

This is 3.6.0-next-20121001.
Comment 4 Chris Wilson 2012-10-18 14:11:32 UTC
Should be fixed with commit fa55583797d12b10928a1813f3dcf066637caf5e

    drm/i915: fixup the plane->pipe fixup code
    
    We need to check whether the _other plane is on our pipe, not whether
    our plane is on the other pipe. Otherwise if not both pipes/planes are
    active, we won't properly clean up the mess and set up our desired
    plane->pipe mapping.

Doesn't contain the the patch I think fixes the assertion failure.
Comment 7 max 2012-10-21 14:58:42 UTC
My bad,
I have lost in so many branches.
Daniel's drm-intel-next-queued (as I guess) at least is used
by ubuntu drm-intel-experimental. It is easy to test it.
Build a random commit takes more than two hours on my laptop.
I have not test the proper commit yet, sorry.
Comment 8 Chris Wilson 2012-10-23 10:33:25 UTC
max. Daniel has rebased dinq on 3.7-rc2 and so I presume drm-intel-experimental will follow suit (not sure if it is based on dinq or din).
Comment 9 max 2012-10-23 17:25:26 UTC
Thank you very much. 2012-10-23-raring kernel from Ubuntu's
drm-intel-experimental is the most stable build since 12.04 release.
There is no call trace in dmesg output. Today I was not
lucky enough to get kernel/GPU hang or at least messy stale
desktop image in unity+compiz with vblank flood in Xorg.0.log.

However now it is obvious that another regression was introduced
last month or so. It does not connected neither to this bug nor vblank
issues. External monitor does not go to power saving mode after
image is switched to LVDS1. Instead it shows flickered red horizontal
stripe at random position as it was mentioned in
https://bugs.freedesktop.org/show_bug.cgi?id=51616#c11
I will report it as a separate bug later.

Now I can confirm that this bug is fixed.

P.S. Does "din" means drm-intel-nest or drm-intel-nightly?
Comment 10 Daniel Vetter 2012-10-23 18:34:20 UTC
Thanks for the confirmation, closing this as fixed.
