Don't know. I usualy test -mm series. Will test tommorow and let you know
after some reasonable uptime.

Don't know. Did not try recently. Will let you know.

It takes time as these hangs are not easy to trigger. With 2.6.21-rc2-mm1
it was easy -> push the system and watch it die in minutes. With
2.6.21-rc5-mm1 it takes hours (3 hangs in ~15 hours) and not sure how to
trigger it. It just happens from time to time.
