Yes.  It is stuck in an uninterruptable state waiting on
disk I/O so it doesn't even see/get this signal.  When this
has happened before a 'kill -INT 1' won't even get the box
to reboot.  The only way I could clear things up was to
cycle power on the box.  With the box being 2 hours from 
here it makes cycling power something I'd rather reserve as
my very last alternative.
