Hi Jan, [taking this on the list after several mails with Philippe...]

[...] I have a problem with the timer on my MacBook Pro (Core2Duo, used in _32_ bit mode)(*): when Xenomai takes over the timer (at 'modprobe xeno_native' time), the Linux timer stops. Looking into /proc/xenomai/irq shows that Xenomai does receive the hardware interrupts, and /proc/interrupts shows that they are no longer forwarded to Linux. Before loading xeno_native, everything is ok. Linux userspace continues to somewhat work: I can issue commands, and depending on the syscalls they made I suppose (no, strace doesn't work), sometimes they end correctly sometimes they hang (and I cannot interrupt them by ^C or other signals.). I tried several .config variations, without any change in behaviour: my current test config has SMP, NO_HZ, APIC, PREEMPT, HIRES all disabled). This happens with a 2.6.22.9 kernel, adeos-ipipe-2.6.22-i386-1.10-07, xenomai svn HEAD (rev 3050), with or without your current patch. It is quite possible that this is not a new problem, since I have this laptop since a few weeks only and I never ran Xenomai on it. I'll happily provide any further information or test results if you need. Thanks, Stelian. (*) yeah, I know I could install a x86_64 distribution but I had some terrible experiences in the past - mainly due to the usage of some proprietary bricks like flash, java etc. I know some of those have been resolved today, and one of these days I should try once more, but now it is not a good time for this. -- Stelian Pop <[EMAIL PROTECTED]> _______________________________________________ Xenomai-core mailing list Xenomai-core@gna.org https://mail.gna.org/listinfo/xenomai-core
