Will do that.

# grep xfs /proc/mounts 
/dev/mapper/wdc1 /mnt/backup xfs rw,nosuid,nodev,noexec,relatime,attr2,delaylog,noquota 0 0
/dev/mapper/wdc1 /data xfs ro,relatime,attr2,delaylog,noquota 0 0

The "/dev/mapper/wdc1" is a dm-crypt device on a ~1TB external disk 
(via FireWire). The 2nd line in the output above is a bind-mount from 
somewhere below "/mnt/backup".

I'm currently trying to reproduce the problem again and see if the 
{dentry,inode}-state output reveals any more information. After that, I'll 
try with noatime.

Thanks,
Christian.
