meer4 boots to blank screen #307

Closed jacobgkau closed 2 years ago

How did you upgrade to 21.10? (Fresh install / Upgrade): Happens when attempting to boot from a live disk, also happens after an upgrade (reported by @mdpetters via https://github.com/pop-os/beta/issues/273#issuecomment-972880828, recreated with live disk in the lab.)

Related Application and/or Package Version (run apt policy $PACKAGE NAME): Kernel 5.15? @mdpetters reports 21.10 boots with kernel 5.13.

Issue/Bug Description: When attempting to boot, after selecting Try or Install from the boot menu, the screen remains powered on but shows nothing. Esc, spacebar, etc don't show any output. The live disk already does not have quiet or splash, so I can't remove those; removing noprompt did not change the behavior (looks like noprompt is just for the CD ejection prompt, anyway). A USB keyboard's backlight does turn off as if it detects an OS, but the keyboard backlight controls don't turn it back on.

Steps to reproduce (if you know): Attempt to boot Intel iso #12 on meer4 (customer & lab unit both have i7-8559U).

Expected behavior: Boots to desktop.

Kernel 5.15.3 from the Mainline app does not have this issue. (The kernel currently being shipped is based on 5.15.2.)

Should be fixed by https://github.com/pop-os/linux/pull/81, updating kernel to 5.15.4.

mdpetters commented 2 years ago

Fixed with 5.15.4 on my machine.
