The system is completely unresponsive.

I believe so.  I have seen this behavior before, on another system.

FYI, I went to the console to reboot.  CTL-ALT-DEL had no [immediate] 
effect.  Then I hit the power button.  Then these messages started 
appearing every 20 seconds on the console:

swap_pager: indefinite wait buffer: bufobj: 0, blkno: 928, size 4096

I will probably power cycle the system to get it back.  Given that the 
system goes unresponsive if I do an camcontrol, what debugging can I 
provide?
