Both known problems: The hang every 10s is hotplug code wasting too much
time (and hence stalling mouse updates). The warning is harmless, the code
wasn't changed at all, it just started reporting possible causes for
flicker. Both problems have patches in drm-intel/drm-intel-fixes that
should land in -stable sooner or later.
