I applied Rajkumar's patch to disable msi-x today, so maybe that will be the end of those problems. I think upstream might want a warn-on for that wmi issue, even if you don't add the work-around code though...just to see if someone else hits it. If you drop the wrong WMI message, often your best hope is that firmware crashes right away, so we should really be quite loud about not sending a WMI message.
