I have a script (thanks to Aneesh) which executes a series of
test(like fsstress, fsx-linux and resize) with various ext4 mount
options (data=journal, data=ordered, data=ordered,nodelalloc
with 1024/4096 as size). While executing the above script for the
first time i ran into this bug.

After the initial run i have rerun the tests 4 time now, but
have not been able to recreate the same issue. [Although 4th time
i ran into another issue. Will start a separate thread for that.]

As for this issue not sure how to proceed further. I probably will
continue to execute the tests few more times. Maybe will try on
a different box.

thanks
