Re: [LAD] Timers, hpet, hrtimer -> kind of solved (for too old motherboards)

From a mail I wrote yesterday to another list: "the good news is, that using HR timer will cause less jitter than the usage of any other timer. The bad news are - Open Octave will freeze the system when selecting HR timer - Qtractor is fine with HR timer, BUT only when I start a project. Once I closed it and try to load it again (even after doing a reset) I get this error: "This system has no accessible HPET device (Device or resource busy)"" [1] "2.6.31.5-rt18 x86_64 and run jackd -Rch -dalsa -dhw:0 -r96000 -p512 -n2 -Xseq. JACK is jackdmp 1.9.3. The self build kernel might be buggy."
