I need to press power button to reset. Then I compiled kernel 4.4 and in this case without any nomodeset or i915.modeset=0 I get login prompt. I attach dmesg when kernel 4.4 is running. Note that in dmesg there is no line about switching to inteldrmfb from EFI VGA after which the hang (kernel 4.9) or black screen (kernel 4.14, 4.15) happens.</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>
