Interesting...

The only bug so far I saw is the following one

https://bugzilla.kernel.org/show_bug.cgi?id=196397

...and above commit fixes it.

Can you place somewhere the bundle of the following:

1. Output file (tables.dat) of
	% acpidump -o tables.dat
2. Output of
	% cat /proc/interrupts
3. Output of
	% lspci -vv -xx
4. Output of
	% grep -H 15 /sys/bus/acpi/devices/*/status

?
