Read again what I wrote: I do not say you "have to", I say "you may want to", it is just a trick you may want to try, which I have already seen solving this kind of issues. Besides, that is what the linux clockevent driver does. I would first try reading the status register in the __ipipe_mach_acktimer , and if it does not fix the issue, try the re-read trick. -- Gilles. _______________________________________________ Xenomai-core mailing list Xenomaiemail@example.com https://mail.gna.org/listinfo/xenomai-core
