Ok, so this is not our bug (at least at this point). I suggest opening a bug at
bugzilla.kernel.org under the Power Management component, attaching a dmesg log
taken with the initcall_debug kernel parameter and using serial or net console.
If possible you could try narrowing down the issue by disabling drivers,
starting perhaps with the one initcall_debug shows as a culprit. If you manage
to get the dmesg log, you could also send a report to lkml referencing this and
the bugzilla.kernel.org bugzilla ticket.</pre>
