Sorry, I already responded in a separate e-mail (see below), butthat obviously missed all the Ccs. So here it goes again...: I'm betting commit a953e4597abd51b74c99e0e3b7074532a60fd031Author: Mike Travis Date: Mon May 12 21:21:12 2008 +0200 sched: replace MAX_NUMNODES with nr_node_ids in kernel/sched.c will fix this if it's not in -mm2 already. The BUG() is simply there to prevent silent corruption. Mike alreadyhas a patch that changes it to a WARN(), but it obviously didn't getthrough (either)...
