[Bug 1501993] Re: drivers/gpu/drm/i915/intel_display.c:12326 check_crtc_state+0x2c5/0x440 [i915]()
Hi Chris,
When using Google, A14 showed up as the latest, and I had tried that
before the bug report. D'oh! I've just upgraded to A15, and I'm still
seeing the problem. Here's the new dmidecode output:

After the bios install, and then booting into the 4.2.0-12 kernel,
here's some of the syslog entries I'm getting:
