Hey guys,

I'm running the new Xenomai 2.6.2.1 with 3.5.7 Kernel on a x86 machine.
I tried several kernel configurations, but I haven't found the right one yet.

The PC (ADLD25PC) uses a PEAK-Systems PCIE/104 CAN interface and two serialport devices.

I have selected the CAN driver and 16550A driver as kernel modules. 

With kernel configuration "-xenomai4"  the serial and can devices works, but there are only 2 CPUs detected - so the hyperthreading cores arn't detected.
And I get a message during bootup "BIOS bug, no explicit IRQ entries, using default mptable. (tell your hw vendor)."
This is my "best" solution so far - CONFIG_ACPI is completely disabled.

In "-xenomai5" configuration is ACPI enabled as you can see in the attached kernel configs.
The mptable message disappears, 4 cores are detected, but serial and can device IRQs get disabled.
The can interface and a usb hub get IRQ 19 - thats solvable for me, but the serialport on IRQ 4 gets disabled and I don't know why. (lspci -v log is also attached)

Could you point me in a direction how to combine the advantages of the two configurations?

Thank you,

Christopher
