Comment 31 for bug 1911352

Just a note: in attempting to fix this issue I borked my laptop - after disabling UEFI boot and then re-enabling it in the BIOS settings, I couldn't boot at all. So I reinstalled Ubuntu and then was getting the following issue after doing system updates (but still on the 5.4 kernel): https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1842320, which showed "error: out of memory" when GRUB was trying to hand over to the kernel. The fix (workaround) for that is to set GFXMODE=800x600 in the GRUB config. And now the software updates *and* the 5.8 kernel works fine ... which is kind of odd.

It's possible that this issue was actually that one, just that we weren't seeing the error message because GRUB is set to hidden by default. Though that doesn't explain why the 5.4 kernel worked with software updates earlier ... still a bit of an unknown, so keeping this open for now.
