Peter, is my kernel configuration ok ? Or should I set some others options
to no ?

Best regards,

Antoine

Why don't you use 2.6.21?
With the tickless timers came a lot of problems which were fixed in the
2.6.21-rc* kernels. However, there are patches for kernel version prior
to 2.6.21, so if you really cannot upgrade to 2.6.21 for some reason,
you may want to try a patch for 2.6.20 from
http://www.tglx.de/projects/hrtimers/2.6.20/ . The name tickless was
introduced with 2.6.21, with this patch it's called dyntick -
technically it's the same thing. On top of that you get high resolution
timers, both were introduced in 2.6.21 together and developed together
before. Using high resolution timers with tickless is recommended AFAIK,
but I don't know too much about this.

But as I said, prior to 2.6.21 this was kind of buggy and may result in
kernel panics, freezes, ...
