 Can you get a crashdump and do the following in kgdb on the dump:
 
 - stack trace ("bt")
 - go to the frame of acpi_video_vo_destroy
 - "p *vo"
 - "p voqh"
 - "p *voqh"
 
 It looks like it is dying in the STAILQ_REMOVE() at the bottom of 
 acpi_video_vo_destroy(), but I need more info to see why.
