Hi Con and Ingo!
What would be the best CONFIG_HZ value for scheduler testing? I used
1000HZ for a long time, but use 300HZ since 2.6.20. This worked well
enough for sd-0.46 and previous versions and ck patches...

Any recommendation? I thought 300HZ was nice two to its compatibility with
PAL and NTSC refresh rates, but then I have notebooks with LCD displays
and do not use any TV cards whatsoever and it might be totally irrelevant
to me.
Well 2.6.21 is out so I may switch to DYNTICKS soon anyway...
About scheduler test results on my two ThinkPads... These are just two
ThinkPads - so my results are not that representative . By contacting the
people on the linux-thinkpad mailinglist it might be possible to get
broader test results[1]. I would be providing my precompiled kernels as
Debian packages if you desired - they should work with Debian Etch, but
they use libata PATA drivers.
