When i try to boot a kernel higher than 2.6.21-rt1, it boots very
slowly. It takes minutes to even detect two cdrom players. I noticed
in the changelog:

- x86/64 high-res timers and dynticks update (Thomas Gleixner)

I included the .config from 2.6.21-rt1, which i ran make oldconfig on.

I cannot provide any other information, since i estimate it will take
ages to bootup.

Does the same problem show up with

http://tglx.de/projects/hrtimers/2.6.22-rc2/linux-2.6.22-rc2-x86_64-highres-v1.patch

tglx

I see the slow bootup as well, even with 2.6.22-rc2-hrt1. It takes at
least 5 times as long to boot, for X to start, to login, etc.
