These mean that you have some other interrupt threads or processes running at a higher priority than the IRQ 8 thread, which are delaying the handling of RTC interrupts. Setting IRQ 8 to RT priority 99 should make them go away. > - Could someone tell me, more clearly than in the kernel > help :), > what's the use of this HPET beast ? It's just another hardware timer that's standard on modern chipsets, like the PIT or the RTC. It's probably not detected correctly by your kernel. > - Does it matter to disable it for real time audio purposes ? Most likely no. Lee
