 Becaause kern i915 was recently updated. mesa was fine for most people.
 netbsd doesn't have a debugger that works for firefox.
 unfortunately the backtraces are all in the segv handler it has.
 
 this is the best info I can have from drm debug messages

 i915 has a lot of video corruption that seemed like something not being
 cleared so I wonder if that is the same thing.
