Title:
  Black Screen on 18.04 + Intel Graphics with Kernel > 4.15.0-47

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Hi,

  we've been running 18.04 (w/ Xubuntu) + 4.15.0-47 kernel for a while
  now (on Minix Z83-4 devices w/ Intel X5-Z8350 CPUs), which is working
  fine.

  After upgrading the kernel to a newer version (> 4.15.0-47), HDMI
  output is not available anymore, i915 reports an invalid EDID version
  via dmesg I dropped the full dmesg output on Pastebin:
  https://pastebin.com/jXTqAzkQ

  As a start I'm blaming the Linux kernel since booting 4.15.0-47 kernel
  works just fine.

  Known faulty kernel versions are:

  - 4.15.0-58-generic
  - 4.15.0-59-generic
  - 5.0.0-25-generic

  Not sure how to best collect logs and system information for you since
  I'm not used to debugging black screens. However, SSH access is
  possible. I am happy to provide more information, if needed. We can
  also install and test experimental kernel versions.

  Note: This happens then attached via a standard HDMI cable as well as
  with a HDMI-DVI cable on different monitor setups.
