Hello,
I'm using the cpufreq ondemand scaling governor for my athlon64 system. My
problem is every time the governor is scaling up the cpu frequency, my sound
is stuttering for a second. I'm using jack for my sound output. First
everything is ok the daemon is starting up without a delay. But if the cpu
speed goes high I'm getting a continuous delay of ~30694.000 usecs...
At the moment im using 2.6.9-ck1. The problem exists also in 2.6.9 and every
other 2.6 kernel, that I've used before with this feature. Before 2.6.9 I had
used the cpudyn daemon for it, there occur the same problem.
