https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D220277 --- Comment #12 from Mark Johnston <markj@FreeBSD.org> --- I managed to capture the hang in ddb using boot -d. thread0 is mtx_sleep()i= ng 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. --=20 You are receiving this mail because: You are the assignee for the bug.=
