--- Comment #12 from Mark Johnston <markj at FreeBSD.org> ---
I managed to capture the hang in ddb using boot -d. thread0 is mtx_sleep()ing
in AcpiOsAcquireMutex() with a stack that goes through acpi_button_probe(). A
taskqueue thread is pause()d with the following stack:

pause_sbt()
AcpiExSystemDoSleep()
AcpiDsExecEndOp
AcpiPsParseLoop()
AcpiPsParseAml()
AcpiPsExecuteMethod()
AcpiNsEvaluate()
AcpiEvaluateObject()
acpi_cmbat_get_bst()
acpi_cmbat_init_battery()
<taskqueue stuff>

I presume that this thread is holding the ACPI mutex that thread0 is waiting
for. So it seems that r310336 wasn't sufficient.
