[Xenomai] Xenomai-3 booting problems

[Leopold Palomo-Avellaneda <leo@alaxarxa.net>]

Hi,


I have compiling a Cobalt kernel. I have followed the web "wikipress" [1];-) 
recommendations. However, my box (a normal desktop computer - Dell Optiplex 
7010 -) doesn't boot. It throws a message like:
....
timer doesn't work through interrup-remapped IO-apic

...

enabling noapic in the boot options I'm able to boot. But, I have not make any 
test by now. Some interesting messages:

$ dmesg | grep -i xenomai

So, can avoid to pass the noapic parameter to the kernel to boot?

Thanks,

Leopold
