You mean a spin after panic?  Then there should be a panic message.  If
it's a total hang with no messages at all, then you can't really know where
in the code it's hanging (i.e. if it's a panic at all).  If the same
situation used to reboot and started hanging when you inserted a
spin-forever loop, then it's a reasonable assumption that your changed code
got hit.  So are you saying you think it is hitting panic but the message
is not getting out to your screen at all?
