  That looks a bit odd.  Line 210 is "numchecks++;", where "numchecks" is a
static variable.  There is no reason why that should involve reading from
0x10018.  My personal suspicion is that this is probably a hardware fault; I'd let
the machine run some more and see if it panics again in the same place or
somewhere different next time. :-)
