But the test on elevator=as (2.5.70-mm9 kernel) still failed, same problem. Some fsx tests are sleeping on io_schedule().
Next I think I will re-run test on elevator=deadline for 24 hours, to make sure the problem is really gone there. After that maybe try a different Qlogic Driver, currently I am using the driver from Qlogic company(QLA2XXX V8).
Thanks,
