Hi,

I am curious, how many of you play with kernel schedulers that are not
in mainline?

To name just a few, there is CFS:
http://www.linuxinsight.com/cfs-sche...el-2.6.23.html

And there still is ck1 for 2.6.22 (and previous), but there will not be
for 2.6.23 or beyond:
http://members.optusnet.com.au/ckolivas/kernel/

I have used both, with good results "feeling-wise" but statistics-wise
there only is the current flame war on the kernel list, ultimately the
reason that Con Kolivas quit.

I am currently running Debian's:
hugo@debian:~$ uname -a
Linux debian 2.6.22-1-k7 #1 SMP PREEMPT Sun Jul 29 07:39:18 CDT 2007
i686 GNU/Linux

to which 2.6.22-ck1 has been added.

Hugo

^^^^^^^
Is this because of the -ck patch?

To answer your question, no, I generally use only stock Debian kernels.

I mean the 'PREEMPT' (if there are troubles with the alignement).

I follow the Debian guide to recompiling its 2.6.22-1-k7 completely,
except, I apply 2.6.22-ck1, apply debian-logo patch and change these
configs:

Preemption Model (Preemptible Kernel (Low-Latency Desktop))[*] Debian GNU/Linux Open Use logo[*] Show timing information on printks
