Speaking of generic vs quirk (if storm can be detected): detection should be eager as ever possible. Too eager does not cause systems failing. This way I think we can converge to stability fast as possible. Then, later on, if a system where interrupts should work but the detection disables interrupts we can either make the fixed threshold less eager, or add a tuning parameter to sysfs. BR, Jarkko
