Don't you just love how well our community works - one reports a bug and someone else has already bisected it and thus saves one the work?! :-))) Thanks Nathan, I can confirm your bisection. The commit above doesn't revert cleanly ontop of linux-next so I tried it and the patch before it: 78ffa3e58d93 ("thermal/core: Add a generic thermal_zone_get_trip() function") <- BAD 62022c15f627 ("Merge branch 'pm-opp' into linux-next") <- GOOD so it looks like that one is somehow b0rked.
