It is almost impossible to run any commands after freeze, even ssh connections
stop working. But I was able to check i915_gem_pageflip contents using a watch
command and continuously appending file contents to a temporary file.
Here is some part of the file I got:
No flip due on pipe A (plane A)
No flip due on pipe B (plane B)
