Same here on precise amd64. Booting with 3.2.0-39 X hangs shortly after login with the earlier mentioned hangcheck messages in the kernel log (machine is remotely login:able). Reverting to 3.2.0-38 yields a stable machine.
This is on a machine with an Intel i5 CPU on an ASUS P8H67-V motherboard, with the latest&greatest BIOS (upgrading the BIOS made no difference). ** Tags added: regression-update -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to a duplicate bug report (644740). https://bugs.launchpad.net/bugs/946899 Title: [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed...
