Hi everyone: Just a follow up on the fast clock issue: "Can you double-check that 'cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq' outputs the same number as your 'cpuKHZ' setting in your config.ini file?" There is no cpufreq directory under /sys/devices/system/cpu/cpu0; all I see is "cache" (dir), "crash_notes" (a file) and "topology" (dir). However under /sys/devices/system/clocksource/clocksource0, available_clocksource reads acpi_pm jiffies tsc pit, current_clocksource reads pit. (I put in the line clocksource=pit) in the grub boot up line. Divider=10 in the bootup line causes the boot up process to hang and a reset has to be performed; removing it and the CentOS boots properly. I'm currently using 2.6.18-53.1.13.el5, with boot up options are "noapic nolapic quiet clocksource=pit" (took out divider=10). CentOS clock is going at around 2 seconds per every real second.
