Kernel panic when booting from USB stick to install elementary OS 7

[peteruithoven]

I'm trying to upgrade my laptop to OS 7 but I'm running into a kernel panic. This while I can boot into Ubuntu 22.04 created in the same way, booting from the same USB stick.

I'm on a Dell XPS 15 9550 (with NVIDIA GTX 960M). I'm using the same USB stick, USB port and Balena Etcher install.
I've used balenaEtcher-1.14.3-x64.AppImage
For both I went into bios to put usb drive as first option in the boot sequence.

I've Downloaded Ubuntu 22.04.1 (ubuntu-22.04.1-desktop-amd64.iso)
Selected: Try or install Ubuntu (first option)
Boots just fine into welcome install screen.

Downloaded elementary OS (elementaryos-7.0-stable.20230129rc.iso)
(using magnet link)
I've verified the checksum following: https://elementary.io/docs/installation#verify-your-download
When booting I select the Try or install elementary OS option.

I get this error momentarily:

error: Out of memory.
Press any key to continue...

And then the following kernel panic:

I've tried reflashing and booting again.
I've also tried the Save graphics option.
Both fail.

Ubuntu 22.04 is what elementary OS 7 is based on, I don't understand what could be going wrong here.

I ran into elementary/installer#542, which resulted in this PR. Building the ISO based on that PR following these instructions, flashing that to an USB stick and then booting from it seems to work!

I am experiencing this problem on my XPS 13 9370 (4K Touchscreen). I attempted to apply the proposed fix to the grub config file (gfxmode=800x600,auto) and build from main on Ubuntu 22.04, but the problem persisted. I have not tried to build from elementary/os#609 directly -- it is now pretty far behind.

In the meantime I installed Ubuntu 22.04 on this machine and have had no issues on that OS.
