Hi Dave,

No it does not. Just sits there any access to mount
point (ll) also blocks forever.

I must point out that I brought the changes from
2.6.28.4 xfs into my private space and that seems to
show improvement on test 008 however now test 011 dies
with kernel oops.

Please see my reply posts.

Thanks,
Rakesh
