[mythtv-users] time loss...

[Graeme Wilford]

Try using a different clock source. Motherboards have several clock
generators and 2.6 kernels can use tsc, pit, cyclone or pmtmr. 2.4
used pit, early 2.6 kernels I tried used tsc and now they use pmtmr.
Some of the clock sources are affected by power-management on some
boards.

append 'clock=<clock src>' to the kernel commandline, where <clock
src> is one of the above.

Check kernel logs to see which one you're currently using:
[root at mythtv1 ~]# grep timesource /var/log/dmesg
Using pmtmr for high-res timesource

Cheers,
Wilf.
