We turn off interrupts first, only then we cancel the hpd stuff (including the modeset_retry work) which presuambly was already running and told fb_helper that stuff happened, then the fb_helper proceeds to do a modeset while interrupts are already off and we're in the middle of tearing down the driver, and all hell breaks loose as a result. Unrelated to these patches, I *think*. I'll hit retest anyway to make sure. -- Ville Syrjälä Intel
