Verified -- reverting the vmscan.c changeset (attached) fixed my hang.
Can we get a sysrq-M dump from that machine please?
alas, for the 'hang' case, my during-initscripts console is going to
strange place. here's sysrq-m from 2.6.9-rc3-bk4 with the mm/vmscan.c
patch reverted (the its-fixed version).
