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!
