I run 50 fsx tests on ext3 filesystem on 2.5.70-mm6 kernel. Serveral fsx 
 tests hang with the status D, after the tests run for a while.  No oops, 
 no error messages.  I found same problem on mm5, but 2.5.70 is fine.

 Here is the stack info:

Thanks for this.

Everything is waiting on I/O.  It looks like either the device driver
failed or the IO scheduler got its state all screwed up.

Which device driver are you using there?

I am usering Qlogic qla2xxx V8 driver

If you could, please retest with "elevator=deadline"?

Sure.

And I saw sysrq on 2.5.70-mm6 failed on my test machine, 2.5.70-mm5
works.  I could trigger sysrq by send"t", but the stack info for all
threads are the same ---the stack info of the sysrq itself.
