Good news at last !!! It seems that the source of the problem has been identified upstream.
Until it is fully solved, hovewer, you can try a workaround. Just edit the config file (1st option for burg, 2nd for grub): $ gksudo gedit /etc/default/burg & $ gksudo gedit /etc/default/grub & and add the "i915.i915_enable_rc6=0 option to GRUB_CMDLINE_LINUX_DEFAULT. Should be something like: GRUB_CMDLINE_LINUX_DEFAULT="i915.i915_enable_rc6=0 quiet splash" Then, update boot files with (1st option for burg, 2nd for grub): $ sudo update-burg $ sudo update-grub That's it. Reboot and enjoy your new kernels! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/946899 Title: [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed...
