I'm not sure how you would like to handle this, but a similar fix needs to be made in drivers/acpi/osl.c:acpi_os_wait_semaphore(). If interrupts are disabled the timeout argument should be set to 0, so that the routine will call down_trylock() instead of down() or schedule_timeout_interruptible(). Alan Stern
