With that commit I have no more those "run_interrupt_driven_hooks:..." 
messages, but still have hang at boot related to DVD (no hang if DVDs are 
physically unplugged). Moreover, I have only 1 of 2 plain ATA DVDs 
detected in probe messages as cd1 (no cd0 there). DDB's ps show sleep in 
the xpt_thrd (xpt_scanner_thread) at "ccb_scan" and sleep at "caplck", no 
locks are shown by 'show lock'.
