I haven't tried to test with earlier kernels. This was the first
time i ran these tests on this particular box.I run the fsstress
on different type of file systems one after the another (in no
particular order ). Something like ..

* create ext2 filesystem on a device
* run fsstress.
* unmount the device.

I repeat the above steps with ext3, reiserfs and jfs. May be this
combination is causing this problem.

I have seen this problem on two partitions of a power box. Same problem
seem to have been reported earlier against 2.6.25-rcx kernel.
