Probably harmless. 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.
