Doesn't the kernel print out something like "too many spurious interrupts etcetc" in
this case?

Anyhow, any debug option i could turn on? I've tried everything IRQ related, but
that didn't change a bit. I understand it requires a new fw from the board
manufacturer or a quirk in the bootloader, but i would like to get something more
verbose before i ping them.
