Anybody knows how to make sure that the kernel will not mess with the hardware clock every 11 minutes? The proper way would be to use a kernel that doesn't try to do it, but I want to use Arch's standard kernel, which has CONFIG_GENERIC_CMOS_UPDATE=y. Maybe something in /proc? I don't know whether the kernel in my system is even doing it; I don't use ntp, but the documentation doesn't say what triggers the 11m mode, it just gives examples...
As far as I know the only thing that will trigger 11-minute-mode is that an ntp client tells the kernel that it is running. To check if it is active you want the adjtimex systemcall. I don't think we have any program in our repos that coneviently displays this, so you'll have to make it yourself or find a snippet somewhere online. -t
