> We hit the BUG again on a third test box -- at least it's fairly easy to reproduce.  Has anyone had a chance to poke at this, or have a suggestion for something for me to try/test?

Have you tried raising /proc/sys/vm/min_free_kbytes ? When I was seeing 
a similar "unable to handle kernel paging request" error on some 
machines, I bumped mine up to 32768, and it seemed to eliminate the problem.
