           Summary: BUG: scheduling while atomic: swapper/0/0x10000002
           Product: ACPI
           Version: 2.5
    Kernel Version: v2.6.35-6999-g7932aeb
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Other
        AssignedTo: acpi_ot...@kernel-bugs.osdl.org
        ReportedBy: sean...@debian.org
        Regression: Yes


Experienced after pulling the latest mainline commits after a couple weeks of
vacation.

Please forgive me if this is incorrectly filed, I'm guessing that it's ACPI
related due to the notable presence in the BUG() call trace.

Also, not sure if this is related to Bug#16542 or not, as in that case the
reporter claimed it could not be reproduced after a reboot and i have managed
to do so, and the stacktrace is different in the two cases.
