Just to make sure I've done the right thing, here are the steps I took. - commented all lines in /etc/modprobe.d/i915 - update-initramfs -u -k 4.11.0-1-amd64 - reboot into kernel 4.11.0-1 with "drm.debug=0x1e max_buf_len=1M" added in grub - switch to console, save output of dmesg to a file. - reboot into older kernel where the i915 module is removed so I could write this. Please let me know if I've done something wrong. If it can help I can try to make a video of the display so you can see how it behaves.</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>
