We hit this exact same > bug recently with a 3.8-rt kernel. No particular reason. Going through my log of the queue I have to say that it was never in the queue starting v3.8. The only ACPI patches that were dropped are: # ACPI # Dropped those two as they cause a scheduling in atomic failure and # we have no clue why we made those locks raw in the first place. # acpi-make-gbl-hardware-lock-raw.patch # acpi-make-ec-lock-raw-as-well.patch # This one is just a follow up to the raw spin locks # Simple raw spinlock based waitqueue # wait-simple-version.patch # acpi-gpe-use-wait-simple.patch but that wasn't me. In that case I try to bring it back in. > -- Steve Sebastian
