Hi Philippe,

I patched the create_irq() function to start the search for unused interrupts not at
NR_IRQS -1 but from 127.
And this seems actually to work.
It looks like the right track!
That means, that actually the large IRQ numbers are conflicting with the system
interrupts.
However, I wonder why this works with a non-adeos-patched kernel...

Regards

Mathias
