Hi,

I'm still fiddeling with my way to slow netbeans debugger. I just tried to
change the clocksource. That resulted in an error, but apparently worked. Is
that expected behaviour:
root@t40:/sys/devices/system/clocksource/clocksource0# l
insgesamt 0
-rw------- 1 root root 4,0K 2006-03-14 09:31 available_clocksource
-rw------- 1 root root 0 2006-03-14 09:31 current_clocksource
root@t40:/sys/devices/system/clocksource/clocksource0# cat
available_clocksource
acpi_pm jiffies tsc pit
root@t40:/sys/devices/system/clocksource/clocksource0# echo acpi_pm >
current_clocksource
-su: echo: write error: Das Argument ist ungültig
root@t40:/sys/devices/system/clocksource/clocksource0# cat current_clocksource
acpi_pm
root@t40:/sys/devices/system/clocksource/clocksource0# echo tsc >
current_clocksource
-su: echo: write error: Das Argument ist ungültig
root@t40:/sys/devices/system/clocksource/clocksource0# cat current_clocksource
tsc
Das Argument ist ungültig = Argument is invalid.
dmesg says:
Time: acpi_pm clocksource has been installed.
Time: tsc clocksource has been installed.

regards
Alex
