kernel panic - umount xfs partition

[Zbigniew Komarnicki]

Hello,

I have a Dabian 5.0 and FreeBSD 7.2-RELEASE-p2 on i386 athlon-xp. I have two  
partitions under Debian. They are xfs file system.

So I mount it from FreeBSD

# mount -t xfs -o ro /dev/ad0s1 /mnt
# ls /mnt
# umount /mnt

Everything is OK, but now I  do the following

# mount -t xfs -o ro /dev/ad0s2 /mnt
# ls /mnt
# cp /mnt/my_file /home/zbigniew

when cp finish the system was frozen and after a while do reboot.
After reboot I saw coredump on the swap file.

This is only for me or also maybe you have such problem. My system is for 
desktop usage. I work at school.
