No, it doesn't change a thing. What does change something however is CONFIG_X86_UP_IOAPIC. Without it (UP or UP+APIC), latency works (albeit with higher latencies - up to 30 us - than with 2.6.20+xeno-2.3.4 - where I saw latencies up to 20-25 _in_SMP_mode_). With IOAPIC I get code 19. -- Stelian Pop <[EMAIL PROTECTED]> _______________________________________________ Xenomai-core mailing list Xenomaifirstname.lastname@example.org https://mail.gna.org/listinfo/xenomai-core
