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

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
