[SOLVED] Blank screen on boot after kernel 6.3.9 -> 6.4.1

I've been running arch on my hybrid i915/nvidia laptop for years, but after upgrading to 6.4.1 i get blank screen right from the initrd image.

it appeared the machine had booted into X since I could blindly use the keyboard to launch a terminal and successfully issue a reboot command.  i had no joy connecting an external monitor though to see what was going on.

to fix it i added the kernel parameter 'nomodeset' to the boot cmd line, which made X fail to start but allowed me to downgrade linux and linux-headers packages back to 6.3.9 from the tty/console which then allowed successful boots into X as normal.

i've added linux and linux-headers to the ignored packages in pacman.conf until i hear more about what's going on.  i suspect an issue with intel's i915 driver.

Please post the full system journal from a boot with the issue.

reverting commit ca62297b2085 fixes the problem.  some discussion over on intel drm i915 issue tracker here and here

Re: [SOLVED] Blank screen on boot after kernel 6.3.9 -> 6.4.1

So likely the same as https://bbs.archlinux.org/viewtopic.php?id=287418 & https://bbs.archlinux.org/viewtopic.php?id=287415
https://bbs.archlinux.org/viewtopic.php?id=286935 has a distinctly different EDID from those, can you post your xorg log or edid?
