Patches are actually merged, so this looks more like a new issue. Also, we already have a report of a sighting of this warning after these patches have been merged, hence marking as a dupe *** This bug has been marked as a duplicate of bug 42907 *** Created attachment 72925 [details]
/proc/interrupts
For completeness I am adding some more info about my system.

I just wonder whether it was related to "[drm] MTRR allocation failed. Graphics performance may suffer." message in dmesg or not. Needless to say, I still have the message, even with 3.4-rc3. |
