Dear Prakash and Mr. Chanteperdrix, I just tried the options (noapic and nolapic) suggested by you and now every time it boots up correctly with Xenomai patch. However, as mentioned by Mr. Chanteperdrix it will create a problem if APIC and IO APIC are supported by kernel, Xenomai would try to use them and it'll create a problem since they are no more supported.
Nevertheless, would it be possible to identify a real cause of this behavior? (why it boots with noapic and nolapic but not without them) I would say it's valuable inputs for us to analyze this issue in more detail and resolve them.

That is not going to work: if APIC and IO/APIC support are selected in the kernel, Xenomai will try and use them, and if you pass these options, it will not be able to use them. -- Gilles. _______________________________________________ Xenomai-help mailing list [email protected] https://mail.gna.org/listinfo/xenomai-help
