I replaced the TOD parts of the kthrt patchset with TOD B10. It seems
there is something wrong with 'c3tsc' and 'pit', though.
c3tsc appears to run fast:
14 Nov 12:02:13 offset: -0.00247 drift: -2502.0 ppm
14 Nov 12:03:14 offset: -0.145203 drift: -2342.5 ppm
14 Nov 12:04:14 offset: -0.329381 drift: -2700.10655738 ppm
14 Nov 12:05:14 offset: -0.532767 drift: -2927.46703297 ppm
14 Nov 12:06:15 offset: -0.638096 drift: -2626.04115226 ppm
and 'pit' seems to produce errors (system will not switch from pit to
another clocksource anymore):
