This is on the 2.6.10-rc1-mm5 kernel with one compile fix patch

Machines are the OSDl 2 and 4 CPU boxes. 
Test is reaim with the 'new_fserver' workload. The 'compute' and 'database' workloads aren't 
showing this.

I see the BUG on ext3, reiserfs, xfs and jfs. 

System usually completes the test run, and performance isn't off too much :)
--------------------------------
With ext3, get this at the start of the run
