I installed the 5.15.0-71 kernel on Ubuntu 22.04.2 LTS and at some point, I noticed that when I boot my AMD Ryzen 3 2200g desktop, I get the GRUB menu after:

error: cannot allocate kernel buffer
error: you need to load the kernel first.
Press any key to continue..._

[something something backup not working either]
Press any key to continue..._

Secure Boot is off, and I only have integrated graphics.

Unlike the other question, the one about a Ryzen 7600 system, I'm not having just a majority of boot attempts being failures, I've never gotten the kernel to boot.

Does it matter that my 5.15.0-70 kernel works fine, except for getting the ACPI Error?

Also, my GRUB file for update-grub is:

GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=30
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT=""
GRUB_CMDLINE_LINUX=""

Timing out for far longer than the known working for some, of 5. No dice.

I had the same problem on my Lenovo IdeaPas 1. After reading the posts none of the suggestions worked. However, people were talking about graphics cards so I thought I'd just try blindly playing around with grub settings.

Uncommenting this line only worked for me:

GRUB_GFXMODE=640x480

I tried 1920x1280 and this didn't work, but 1024x768 does.

Hope this helps to get others booting and gives those how know what they are doing a pointer :)
