Unfortunately, the only errors listed are the ACPI ones from early in the boot cycle (and the response for the ACPI devs was that they don't see how those could be related to problems with the internal monitor). This is a video of what the freezing misbehaviour looks like on my machine: <a href="https://www.dropbox.com/s/hjenwbeitamnnp5/2017-08-07%2009.59.28.mp4?dl=0">https://www.dropbox.com/s/hjenwbeitamnnp5/2017-08-07%2009.59.28.mp4?dl=0</a> <a class="bz_bug_link bz_status_CLOSED bz_closed" title="CLOSED INVALID - [BDW] Freezes, whiteflash and flickering on kernel 4.11 and 4.12 Intel HD Graphics 5500" href="show_bug.cgi?id=101380">Bug #101380</a> was a previous report of a similar issue, and their video is what made me believe they were encountering the same problem: <a href="https://www.dropbox.com/s/4ffyk8ddtht2w10/example.mp4">https://www.dropbox.com/s/4ffyk8ddtht2w10/example.mp4</a></pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
