[Bug 1970402] Re: Initrd out of memory error after upgrade to 22.04

[Edgardo Marchi]

I can confirm this issue after upgrading from 21.10 to 22.04.
In my case, the fix only comprised changing MODULES=most for MODULES=dep in /etc/initramfs-tools/initramfs.conf. Changing the compression algorithm doesn't seem to have impact on my setup.
Before the change, initrd had 234 MiB in size versus 106 MiB after. I have 64GB of RAM.

  After upgrading to 22.04 system is unbootable because of "out of memory" error when loading initial ramdisk. I was able to fix it by editing cat /etc/initramfs-tools/initramfs.conf
