Bug#412194: further information / possible fix



Dear maintainers,


after looking around in dmesg and other logs i finally found a disparity:


While linux-image-2.6.17-2-k7 is booting with following clock:

#Real Time Clock Driver v1.12ac
#Generic RTC Driver v1.07


The linux-image-2.6.18-4-k7 uses pit as clocksource:

#Time: pit clocksource has been installed.


After further digging in the kernel archives and some boards i found that AMD-MPX-Chipset and dual cpu AthlonMP driven boards like mine preferably run with acpi_pm as clocksource.

Just one happy case (same strange error, same idea working as a solution):

However, after adding

"clocksource=acpi_pm"

as an additional boot option for linux-image-2.6.18-4-k7 it still seems to be ignored, as following dmesg-log-entries show:

#Kernel command line: auto BOOT_IMAGE=Debian root=801 clocksource=acpi_pm
#...
#Time: pit clocksource has been installed.


Is there any other way i can force the correct clocksource?


Thank you once again!
