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.

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.

Most likely no.
