Well I found out why, I compiled i915 into the kernel it seems, at least I don´t have an i915 module in lsmod. But also i915.i915_enable_rc6=7 on kernel command line does not seem to have any effect.

Too early to say for sure, but it seems something in UXA may have triggered it more easily. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1140716 Title: [regression] 3.5.0-26-generic and 3.2.0-39-generic GPU hangs on Sandybridge Status in Direct Rendering Infrastructure: In Progress Status in Mesa: Unknown Status in linux package in Ubuntu: Invalid Status in linux-lts-quantal package in Ubuntu: Invalid Status in linux-lts-raring package in Ubuntu: Invalid Status in mesa package in Ubuntu: Triaged Status in linux source package in Precise: Fix Committed Status in linux-lts-quantal source package in Precise: Fix Committed Status in linux-lts-raring source package in Precise: Invalid Status in mesa source package in Precise: Triaged Status in linux source package in Quantal: Invalid Status in linux-lts-quantal source package in Quantal: Invalid Status in linux source package in Raring: Invalid Status in linux-lts-quantal source package in Raring: Invalid Status in linux package in Debian: New Status in linux package in Fedora: Unknown Bug description: I'm getting errors about GPU hangs every minute or so (usually only when using FF and scrolling a webpage or something).
