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

    I'll try not to move things too much so I can test this more.
    (You don't think it's critical, do you?)

    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.
