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. Please CC me when replying, because i do not recieve this list. Sincerely, Maarten Maathuis.
