Furthermore, it looks like ALSA is > using the HRTimer: The proper fix for the crash in drumstick-sysinfo will be included in the upcoming Drumstick-0.3.2, when published. The fix shall only avoid the abort signal and the crash, showing to the user a less alarming error message instead. The root cause is the ALSA module snd-hrtimer not loaded, when the hardware providing the HPET timer is available, and it is used by Jack. Loading the ALSA module fixes the crash and allows the ALSA sequencer applications to access this high precission timer. In my opinion, if you run some ALSA sequencer applications with a modern Linux/ALSA and your motherboard provides the HPET, the module snd-hrtimer should be loaded. It is the alternative to the RTC timer present in older machines.
