<pre>I booted 4.7.2 twice, once with drm.debug=0x1e and once with drm.debug=0x06,
see attachments.
Then I removed i915.enable_psr=1 from my kernel parameters, and now everything
appears to work smoothly; I haven’t experienced a single freeze since boot. So
it seems that PSR causes all of these issues. (I haven’t tried connecting an
external monitor yet.) I’ll keep PSR disabled for now.</pre>
