>Description:
I have Linux ext2 partitions which I decided to add in fstab such that 
they are automatically mounted at boot. Thus I added the following line:

/dev/ad1s1         /common   ext2fs    rw,auto           0   0       

in my original /etc/fstab:

/dev/ad1s2b        none      swap    sw              0   0
/dev/ad1s2a        /         ufs     rw              1   1
/dev/ad1s2g        /common   ufs     rw              2   2
/dev/ad1s2e        /tmp      ufs     rw              2   2
/dev/ad1s2f        /usr      ufs     rw              2   2
/dev/ad1s2d        /var      ufs     rw              2   2
/dev/acd0          /cdrom    cd9660  ro,noauto       0   0
/dev/acd1          /cdrom1   cd9660  ro,noauto       0   0

As a result I was happy to see my ext2 partition mounted nicely at boot
time. Unfortunately when I wanted to reboot typing
#reboot

or to turnoff my PC typing
#shutdown -p now

this partition couldn't be unmounted. This was not however the case with 
FreeBSD 4.11 and 4.10 Release. I had no such problems there!

>How-To-Repeat:
Just create an ext2 partition and mount it like above. Reboot such that
it is automatically mounted and then reboot once again!
