Thread: Visible boot slowdown between 2.6.24.3 and 2.6.22.2

  1. Visible boot slowdown between 2.6.24.3 and 2.6.22.2

    Hi,
    I saw a significant slowdown of a bootup time after 2.6.22.2 was
    upgraded to 2.6.24.3. Visibly I can see the issue when the boot process gets
    to running udev - now it sits for good minute or two. I can also visibly see
    a slowdown when I do "ps aux" under the new kernel vs. old one.

    This is a relatively old system - 500 Mhz P3 Celeron with 512M RAM.

    Any debugging suggestions are appreciated...

    Could be the cpu frequency is wrong, could be that the MTRR system went wrong.

    Please send the dmesg output for both 2.6.22.x and 2.6.24.x, as well as the
    contents of /proc/mtrr for both kernels, thanks.

    It's the same for me,too. I tried 2.6.24.3 on my IBM R40, which has 1.4
    GHZ CPU, the boot process is very slow. I didn't run "ps aux". But, I'll
    try that out and let know.

    Please boot with printk.time=1 so that it is a bit easier to see where
    it waits.
