I am booting from the internal HDD, not an external USB drive. I am using Debian Stretch with stable and stable-backports kernels. I tried loading i915 on several kernels: - 4.9.88: Works. - 4.11.6: Works. - 4.12.6: Works. - 4.13.13: Works. - 4.14.13: Works. - 4.15.11: Hangs. - 4.16.5: Hangs. Where it works (<=4.14), there are still warnings and traces in the dmesg logs that might provide some clues as to what is going wrong in later versions (>=4.15). Attached is the dmesg log for 4.14.13.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
