I'm running Dapper (2.6.15-23-386) on a Toshiba A105-S2712. The system boots successfully, but the kernel log keeps posting the subject error message every minute or so. Actually, a group of 6 messages is posted each time, where the last 3 are a repeat of the first 3. They appear to be issued from:

linux-source-2.6.15/drivers/acpi/executer/exmutex.c (line 240)
linux-source-2.6.15/drivers/acpi/parser/psparse.c (line 516)

Here are the messages:

ACPI-0240: *** Error: Cannot release Mutex [MUT1], not acquired
ACPI-0517: *** Error: Method parse/execution failed [\_SB_.RDEC] (Node df7c25c0), AE_AML_MUTEX_NOT_ACQUIRED
ACPI-0517: *** Error: Method parse/execution failed [\_TZ_.TZCL._TMP] (Node df7c97c0), AE_AML_MUTEX_NOT_ACQUIRED

I never encountered this when running Breezy (2.6.12-10-386).
