Hi,

While testing delay accounting patches in 2.6.18-rc1, we experienced
random panics in slab allocation/free routines.

Since we have not seen these panics in earlier version we went back and
tested the same set of patches in 2.6.17, and they behaved as expected.

We ran the same test _without_ delay accounting in 2.6.18-rc1, and saw
random panics. Which when tried in 2.6.17, the test did not fail. 2.6.17
kernel ran for more than 20 hrs without any issues.

Since the bugs were seen in slab routines, I replaced mm/slab.c in
2.6.18-rc1 with the same file from 2.6.17(with a small change). I did
not see any crashes.

By adding one patch at a time to 2.6.17's mm/slab.c, I found that the
removal patch is the cause of the panic.

--------------

To confirm that, i just removed the above patch from 2.6.18-rc1 and the
tests ran successfully for more than 2 hrs. (is still running)

Attached are the config file, panic stack and mkthreads.c file used to reproduce the problem.

Running
"while true;do ./mkthreads 1000 100; done"

leads the 2.6.18-rc1 kernel to panic in 30-60 minutes.

regards,

chandra
