When I use reiser4 on one partition everything is fine. But when I tried to
use it on two partitions - kernel crashed upon doing unmount of filesystems.

I have the same problem. My current workaround is to never unmount them at
all -- I crudely hacked halt.sh to skip trying to unmount filesystems, and
to jump straight to "remounting remaining filesystems readonly". I have to
do "mount -o remount,ro", because "umount -r" crashes.
About this "crash" -- it's an oops at first, then things start to fall
apart. I never quite get a crash, but a reiser4 crash is almost as bad.

Zam mentioned something to me about a race in the umount code he ran
into while benchmarking, could be the same thing, probably he'll tell
you more on monday.
