I have to admit that I did not really understand what your problem is. I
only told you what "Xenomai: xnintr_irq_handler: IRQ10 not handled"
means. Without seeing the driver code, I can not tell you much more,
except that it all boils down to the driver returning XN_ISR_NONE. For
the system to work correctly, when one driver returns XN_ISR_NONE,
another driver has to handle (meaning really making the peripheral
deasssert the irq line) the interrupt and return XN_ISR_HANDLED.
