The current problem I see is that the rest of panic notifier chain won't be called once when we hit the problem in KMS notifier. So, this bug in KMS influences on the rest panic behavior.
Maybe a hackish solution would be to keep KMS notifier at the end of notifier chain so that it crashes at last. I don't like this either, but...
You need to do that with both the kms panic notifier in drm_fb_helper.c and with the fbcon panic notifier. And iirc there's also a console->unblank call somewhere which _also_ can end up in ->set_par. But I'm not sure anymore when exactly that one is run, I've tried hard to forget this all ;-)
Oh well, you're suggesting the need for Propranolol overdose ;)
