Can you please retest with latest upstream git from Linus' tree?

    drm/i915: Sanitize shared dpll state

Could be the fix for the issue you're hitting here.

If that doesn't help please boot with drm.debug=0xe added to your kernel
cmdline, reproduce the backtraces and then attch the complete dmesg.

Thanks, Daniel
