Hmm. I'd really like to know why that's behaving different.

Usually there are only timers in the CLOCK_MONOTONIC base during
boot. CLOCK_REALTIME base should be empty most of the time. If my
theory is correct then the number of reprogram events is correct as
well because base[MONOTONIC]->first is always the one which armed the
timer.

Can you add some debug which tells us to which base the removed timer
belongs ?

Thanks,

tglx
