Just a data point:  I have been using multiple tmpfs bind mounts for some time
on smp without this problem.

none on /dev/shm type tmpfs (rw,nosuid,nodev,mode=1777,size=256M)
/dev/shm on /tmp type none (rw,bind)
/dev/shm on /usr/tmp type none (rw,bind)

Never had a reboot fail for this reason.

Sean
