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
