bind mounts and shutdown sequence

[Stephen Olander Waters <debian@luy.info>]

I am running sid with amd64 architecture. I also have a chroot
called /x86 to run openoffice, acroread, boinc, etc. In my /etc/fstab, I
have several bind mounts into /x86.

When I run "shutdown -h now" or "shutdown -r now", the shutdown sequence
stops with an error after stopping all the processes. I have to use Alt
+SysRq to reboot. However, the shutdown sequence works OK if I manually
unmount the bind mounts before executing "shutdown".

Is anyone else experiencing this problem? 

I can file a bug once I figure out what script is dying (it's hard for
me to tell because the machine is unusable except Alt+SysRq!)

Thanks so much,
