Dan,

This BUG_ON has been demoted to only trigger when DEBUG_VM is set in
upstream:

http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=97ee4ba7cbd30f1858f0d16911e042737c53f2ef

I'm looking into why there's a one page difference between the E820
tables and SRAT. You're right that there seems to be an off-by-one in
one or the other.
