Thanks, It was a guess with no proof.

Let's undo the change above and start adding some print statements to collect
data from your system.

Can you add this to the end of acpi_irq_get_penalty function and then send
the output?

pr_info("%s:%d irq = %d penalty = %d\n", __func__, __LINE__, irq,
penalty);


This produced some 60 lines extra. Too much to include here.
The entire dmesg file is here:
http://webserver.djo.tudelft.nl/dmesg474+printpenalty

Thanks, let's go back to 4.6 and add a very similar printf to every single place where the array is modified and also right before the enabled message.

I am trying to find a system with similar characteristics for debug
