by Hi,
with kernel 2.5.45 I'm unable to unmount XFS filesystems. 'umount' is
blocked in D state:

oldumount("/usr/download" <unfinished ...>
umount blocks here. I was able to umount correctly a ext2 and a reiserfs
partition. SysRq-S and SysRq-U stops when syncing or unmounting XFS
filesystems. No messages from the kernel.
XFS support is compiled in the kernel.
HTH,
Luca
