With r43239 (thx nbd!), the board does not crash anymore but there still
seems to be an irq-related bug. The kernel sometimes spits out

   irq 40: nobody cared (try booting with the "irqpoll" option)
   [...]
   Disabling IRQ #40

in ath_isr, see [1].

Another weird thing: with the same configuration, the wifi devices most
of the time do not come up because the wrong regulatory domain is set
(country 98: DFS-UNSET) instead of (country DE: DFS-ETSI). A log of this
can be found in [2]. If it comes up correctly, the above messages show
up. I don't know if the IRQ message and the regd problem are related.

The config can be found in [3].

Any ideas?

Cheers,
André
