tiobench is having trouble completing in kernels >= 2.5.19 on my K6-2
384 mb ram, IDE test system. The parameters I'm using are:

tiobench.pl --size 2048 --numruns 3 --threads 1 --threads 32 --threads 64
--threads 128

--size depends on ram and disk space.

Early in 2.5, dbench 192 would exercise a bug or two.
(requires about 5GB of disk space)

Linux Test Project's runalltests.sh has occasionally triggered a bug.

2.5 took a drop in dbench throughput recently.

dbench ext2 128 processes Average High Low(MB/sec)
2.5.19 18.60 21.69 14.58
2.5.20 12.89 13.15 12.79
2.5.21 12.67 12.94 12.51

If you want to benchmark some stuff while you're stress testing,
http://home.earthlink.net/~rwhron/kernel/index.html might be a
starting point for ideas.
