I/O regression after 2.6.0-test5
Quoted 1 line
Randy can reproduce regressions, so I'll work on his first.
Below is test8 and test8 with the test5 as-iosched.c (2.6.0-test8-as). Jobs/minute is way up, and total runtime is way down with the test5 as-iosched.c.
The machine (quad P3 xeon) locked up during a bonnie++ run. I can't compare that to vanilla test8 because I stopped the test8 to run the
test5 as-iosched. Both of these were compiled with gcc-3.3.1 because
of the RedHat gcc-2.96 bug in test8. (In case the compiler was part of the instability).
Earlier I ran 2.6.0-test3-mm2 compiled with gcc-3.3.1, and it was stable on this box.

I'm running Nick's patch
http://marc.theaimsgroup.com/?l=linux-kernel&m=106688130229337&w=2
on test8 at the moment. I should have some comparison numbers within 24 hours.
