reiser4: mount -o remount,ro / causes error on reboot

["Peter" <sw98234-PkbjNfxxIARBDgjK7y7TUQ@public.gmane.org>]

Using: gentoo
kernel 2.6.17.11 with beyond patchset
reiser patch 2.6.17-3
reiser4progs 1.0.5

At the end of the gentoo shutdown script is a short function which
remounts / as ro.

sync; sync
sleep 1
.....
# ${x} = /
mount -n -o remount,ro "${x}" &>/dev/null

On reboot or after a poweroff, root does not mount properly, and after
some modules are loaded, there are segfaults when running init scripts.

The init scripts prompts for the root password for maintenance. Simply
typing exit forces an unmount of / and a reboot.

After this, everything is normal. On a normal shutdown, this error cycle
begins anew. Something has changed in the gentoo shutdown sequence as this
error is new to my system. However, gentoo does not support reiser4 as it
is experimental. I wanted to report this.

Remount is required since with the halt script running, the root cannot be
unmounted. After halt.sh, reboot -idpk is called or shutdown.
