Please add the "time" parameter to the kernel boot command line then attach the full dmesg output to this bug report, thanks. Created attachment 13020 [details]

Bart, is that expected? Thanks. (It might be useful if you could also attach the dmesg for a 2.6.22 kernel for comparison purposes) (all your dmesg files are truncated, btw: you'll need to use the log_buf_len boot command-line option, and `dmesg -s 1000000' to fix this) This is not expected. I don't recall any changes in the area of IDE device probing in 2.6.23 so git-bisect is the best way to proceed (and pinging Thomas or Ingo since the facts that clocksource fallback happens just before the long delay and that low latency kernel fixes the issue are highly suspicious). Yes, it could be that the clocksource code changed the time and a short sleep becaome a very long one or something. It would be good if the reporter could reboot the problematic kernel a few times and check to see if that clocksource messages always comes out in the middle of IDE probing. Sorry, kernel 2.6.22.6 has the same problem. delay is not present when compiled as lo latency. Created attachment 13024 [details]
dmesg. kernel 2.6.22.6
dmesg 2.6.22.6, also halting btw, (no lo-latency) During the halt the fan blows at full force, shortly before the boot process continues, the fan quiets down. As far as I can see it always hangs at the same line. I hope this dmesg is not truncated.
Can you please provide the delta of the .config files of the fast and slow booting kernels ?

Is this problem still present? I compiled 2.6.23 in several ways. Maybe strange, but it works fine I think you can remove the bug. Best regards, and than you.
