Exactly the same problem with GRUB occurs on LG Gram 14 (2021) with Ubuntu 22.04.
In my case it means that after upgrading Ubuntu from 21.10 to 22.04, GRUB no longer boots, showing "error: out of memory.". I had to boot another OS from USB which is not Ubuntu 22.04, because live image have the same problem. I`ve used the image of Ubuntu 20.04 LTS. CSM/UEFI and Secure boot enabled/disable - tried all and thats not related to this in any case. After chrooting and regenerating GRUB with GFXMODE set to 800x600, I could finally reach the stage of loading kernel and decrypting the disk. :) It still not booting due to another problems, but thats another case, not related to this problem. The real problem is that I cannot perform clean installation due to not booting USB live image of Ubuntu 22.04 with "error: out of memory.". For now I've tried to repack squashfs with GFXMODE=800x600 change applied and write that to USB stick, but for now without luck (still the same error) which is strange, because it helped in already installed Ubuntu 22.04. Maybe I missed something - I will dig into this later and let you know. I'm gonna also try @ybdjkfd fix. Also, its a little bit frustrating, because if something happens in the future with OS on my PC storage and it stops working, I can't revive it with USB stick with latest Ubuntu, because it's also not working. :) Keeping additional old OS versions on pendrives or specially prepared (with repacked squashfs) is not an ideal solution when sometimes "on the go" you just need to download&write the ISO. It generates unnecessary extra work, mounting/chrooting and systems juggling, so thats a real problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1842320 Title: Out of Memory on boot with 5.2.0 kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1842320/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
