Maybe other (compositing) window managers work too, but I have not tested that. I am using the below bash script after logging into KDE.

Ok, there is one merge conflict with current kernel master, but I am trying to build the kernel now after fixing the conflict in one way (keeping the code). I tried also to merge that with the ilk-pile but that was hopeless with loads of merge conflicts. Will give feedback as soon as I can.

Looks eerily similar to attachment #69604 i.e. has been tried, doesn't work on at least Peter's machine.

Plain 3.7-rc kernel, just pick one that's broken ;-) Please also test the patch in comment #43 since that one tests a different theory.

Is the i915 error state needed? It always happens while I am doing heavy IO things. This time pbuilder/cowbuilder installation tests of 1Gb of new packages on Debian.

A couple of additional test runs at this and its parent commit proves this. I'll try patches from comment #43-#46. Since those didn't fix the problem for Norbert it might be we have multiple issues. Chris: running with enable_hangcheck=0 on #6c085a72 the machine locked up.
