Subject: [2.6.27.6] jfs on raid1 => attempt to access beyond end of device.

hi,

few hours ago i've set up jfs filesystems on raid1 and raid0.
during restoring backup i've got an errors in dmesg.
the testcase on my system is easy and 100% reproducible:
just do the following command on jfs/raid1 device:

# dd if=/dev/zero of=testfile bs=1M count=4096

# fdisk -l /dev/sd{a,b}

any ideas what's wrong?
