If you are so inclined, you could get the cvs kernel from oss.sgi.com, which
has kdb, and when xfs_io hangs you could break into the debugger and issue
a "ps D" to see which threads are in D state, and backtrace them.
This could offer some good clues on where things are hung up.
It might also be interesting to take smb out of the picture; do you see the
same issues with local IO to filesystem on the lvm device? That might be a
simpler case.
