Does this also occur with the drm-intel-next branch? Do you have a
picture of the corruption?

Didn't try this one, went back to 2.6.37-rc4-00292-g3c8cdf9 now.
I thought about following the bisect way, should I go a different
one better?
> Do you have a picture of the corruption?
Not yet, can do one next time. Though I found one that looks
very similar to my corruption:

Though in my case no character was visible anymore.
Cheers,

Bisect would also be fine.

Interesting, ok.

Just went that path, compiled 2.6.37-rc4-00292-g3c8cdf9
and suspended which resulted in a completly dead device
(no ping, no ctrlaltdel possible), i.e. different fatal situation.
I'm a bit confused, not sure whether this is related to
the broken display issue or not.
As the tests always cost a quite lengthy fsck run, I'd
love to go a different way from 2.6.37, if anybody has
a better hint.
Cheers,
Nico

this has been verified to be a duplicate of bug
https://bugzilla.kernel.org/show_bug.cgi?id=27702, and the patch at
https://patchwork.kernel.org/patch/499221/ is a proper fix.
