Hi Sebastian,

your 3.18.7-rt1 kernel compiled without problem. First quick test
shows good latency values (i7 at rack #4, slot #6) and looks
promising. Will continue testing on more machines and architectures.

The cpufreq problem that first appeared in 3.14 - obviously - is still
there. Here comes a workaround that I needed to conduct tests at various
clock frequencies. It may also help to demonstrate the situation.

Thanks,
