           Summary: Unstable clocksource reported
           Product: Power Management
           Version: 2.5
     KernelVersion: 2.6.21.5
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: cpufreq
        AssignedTo: cpufreq@www.linux.org.uk
        ReportedBy: patrick.matthaei@web.de


Most recent kernel where this bug did not occur: Not known
Distribution: Debian Sid
Hardware Environment: AMD Athlon64 San Diego 4000+
Software Environment: Tickless Timer Support (64bit CPU, but 32bit system)
Problem Description:
Every time if I activate the 'ondemand' powersave gorvener, dmesg reports
following:

Time: acpi_pm clocksource has been installed.
Clocksource tsc unstable (delta = -245560788 ns)

This thing needs at booting up ~ 2-10 seconds, which is a lot of time, so I
think this is a bug.

My kernel config with all my inbuilded powersave features etc. is in attached.

Steps to reproduce:
Just do a "/bin/echo 'ondemand' >
/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor".
