This is definitely unexpected. I think we need a bit more data to
figure out what's going on here:
- Please boot with drm.debug=0xe added to your kernel cmdline and grab
the dmesg right after boot-up for both a working or broken kernel.
- Are you using any special i915 cmdline options?

Everything else should be in the debug logs I hope.

Thanks, Daniel
