[BUG] data_access_exception during chroot()

[BUG] data_access_exception during chroot()

[Thomas Bader]

Hi all

I'm running 2.4.17-pre6 on my SUN Ultra1.  Further, I've got devfs, RAID and
LVM support in my kernel config.

Now I'm trying to chroot to a specific directory:

duke:~# mount
/dev/sda8 on / type ext2 (rw,errors=remount-ro,errors=remount-ro)
proc on /proc type proc (rw)
/dev/md/0 on /mnt type ext2 (rw)
duke:~# cat /proc/mdstat
Personalities : [raid1]
read_ahead 1024 sectors
md1 : active raid1 scsi/host0/bus0/target1/lun0/part2[1] scsi/host0/bus0/target]
      627648 blocks [2/2] [UU]

md0 : active raid1 scsi/host0/bus0/target1/lun0/part1[1] scsi/host0/bus0/target]
      3145664 blocks [2/2] [UU]

unused devices: <none>
duke:~# chroot --version
chroot (GNU sh-utils) 2.0.11
duke:~# chroot /mnt /bin/bash
