    notices shown during boot are not an issue. if boot stops it is the NEXT one not shown, and then it is basically almost the video card driver. add nomodeset at grub as a boot parameter and see if it then continues. (reference https://askubuntu.com/questions/716957/what-do-the-nomodeset-quiet-and-splash-kernel-parameters-mean ) – Rinzwind Oct 18 '23 at 17:11

    The acpi notices started appearing with kernel 5.19 and that was due a decision by the kernel developers to stop hiding bios notifications. We users can't fix them, You can suppress them if you want (the quiet kernel parameters has a errorlevel= vith a number that removes most or all messages during boot (number 2 remove acpi warnings) – Rinzwind Oct 18 '23 at 17:15
