[parisc-linux] MD problem

[joel.soete@freebel.net]

and additional problem:
if I mount automaticaly /boot in /etc/fstab it is impossible to dismount this fs:

umount /boot
device busy

fuser -u /boot
/boot
No process references; use -v for the complete list
fuser -v /boot:

             USER       PID  ACCESS  COMMAND
/boot        root    kernel  mount   /boot

Any idea? (if I mount it manualy after the reboot no problem?)
