Some of these are erroneous, for example indicative of untidy bios. This bug is basically a tracker bug for https://bugs.freedesktop.org/58897 first round of patches is here: http://lists.freedesktop.org/archives/intel- gfx/2013-February/thread.html#24866 + + ..but instead of backporting those it makes more sense to just silence + the error messages, since they are harmless. + + [Test case] + just use the machine for a while, these messages appear for instance when suspending/resuming when the VT is shown for a while + + [Regression potential] + none really, it just changes the severity of the messages so that they are not shown by default
