Looks like it's reproducible right now - I got exactly the same
message when I boot again later.

Nope. Just plain old /boot/vmlinuz on a simple IDE disk with
a single ReiserFS partition and ReiserFS code compiled into
the kernel.

Will do it gladly, when I'm back home tonight.

Thanks for everything,

PS I'm not on lkml, so please keep me cc'ed about this.
