I get this one: GEOM: ad0s1: geometry does not match label (15h,63s != 16h,63s). Trying to mount root from ufs:/dev/ad0s1a ACPI Exception (utmutex-0376): AE_TIME, Thread 186B0 could not acquire Mutex [0] [20070320] ACPI Error (exutils-0180): Could not acquire AML Interpreter mutex [20070320] ACPI Error (utmutex-0421): Mutex [0] is not acquired, cannot release [20070320] ACPI Error (exutils-0250): Could not release AML Interpreter mutex [20070320] ACPI Exception (utmutex-0376): AE_TIME, Thread 186B0 could not acquire Mutex [0] [20070320] ACPI Error (exutils-0180): Could not acquire AML Interpreter mutex [20070320] ACPI Error (utmutex-0421): Mutex [0] is not acquired, cannot release [20070320] ACPI Error (exutils-0250): Could not release AML Interpreter mutex [20070320] The problem is it doesnt happens always, but with soft reset there is (perceived) bigger chance to happen. Also kernel without WITNESS and other debug options have much bigger chance for this error to happen. -- Paul
