- Only poll the PCIC controller for insertion/removal events if the
controller hasn't been assigned an IRQ.
So, this means your PCIC controller is busted, and is 'wasting' an IRQ
that doesn't work.
The correct solution is to figure out why the IRQ isn't working, but the
'quick-n-dirty' fix is to re-enable the polling feature.
