Created attachment 294089 [details] Kernel config file. Kernel 5.10-rc7 won't boot on Dell XPS 13 9310 with Intel i7-1165G7 and BIOS Version 1.1.1. I got a blank screen after finishing booting sequence and had to power it off. 5.10-rc6 is OK.

commit ccc9e67ab26feda7e62749bb54c05d7abe07dca9 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Wed Nov 25 19:30:32 2020 +0000 drm/i915/display: Defer initial modeset until after GGTT is initialised is bad.
It is caused by ccc9e67ab26feda7e62749bb54c05d7abe07dca9 is the first bad commit commit ccc9e67ab26feda7e62749bb54c05d7abe07dca9 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Wed Nov 25 19:30:32 2020 +0000 drm/i915/display: Defer initial modeset until after GGTT is initialised Prior to sanitizing the GGTT, the only operations allowed in intel_display_init_nogem() are those to reserve the preallocated (and active) regions in the GGTT leftover from the BIOS. Trying to allocate a GGTT vma (such as intel_pin_and_fence_fb_obj during the initial modeset) may then conflict with other preallocated regions that have not yet been protected. Move the initial modesetting from the end of init_nogem to the beginning of init so that any vma pinning (either framebuffers or DSB, for example), is after the GGTT is ready to handle it.
Fixed in 5.10.0 by commit b1f195fc49812359296a901e26cc7c0b761d8a70 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu Dec 10 23:07:41 2020 +0000 drm/i915/display: Go softly softly on initial modeset failure Reduce the module/device probe error into a mere debug to hide issues where the initial modeset is failing (after lies told by hw probe) and the system hangs with a livelock in cleaning up the failed commit.
