[PlanetCCRMA] f8 kernel, some problems (jack late warnings)

[Fernando Lopez-Lezcano]

In my f7 laptop I'm seeing problems with Jack and the 2.6.23.x kernels
(which are the ones released for f8). Many "late" warning messages and
occassional xruns. It seems to be a problem with system time glitches
when processes move from one cpu to the other (and that causes jack to
report the bogus problems). 

A workaround if you hit this problems is to boot with the "idle=poll"
kernel option, that fixes the problem but of course does not allow the
cores to go to low power modes.
