I must have patched crap into this, but I don't see it. Could someone have a look why there is no printk output related to #IRQ 219 (~0xffffff24, see stack content)? BTW, Mathias, forcing your kernel into single CPU mode via kernel command line "cpus=1" doesn't expose the issue, right? Could we face some kind of setup race across the CPUs here? Thanks, Jan
