Comment 158 for bug 1842320

I also confirm that the proposed update fixed the out of memory error when booting on my computer. The packages I installed and tested:

grub-efi-amd64-bin/jammy-proposed,now 2.06-2ubuntu14.1 amd64 [installed,automatic]
grub-efi-amd64-signed/jammy-proposed,now 1.187.3~22.04.1+2.06-2ubuntu14.1 amd64 [installed]
grub-efi-amd64/jammy-proposed,now 2.06-2ubuntu14.1 amd64 [installed]

The kernel and Nvidia driver installed on the system are:

linux-image-5.15.0-58-generic/jammy-updates,jammy-security,now 5.15.0-58.64 amd64 [installed,automatic]
nvidia-driver-525/jammy-updates,jammy-security,now 525.78.01-0ubuntu0.22.04.1 amd64 [installed]

Since my system hadn't been working because of the error, I had to boot up my computer with a Live CD, mount the filesystem, chroot, add the jammy-proposed repository, and install those proposed packages. My system booted up successfully afterward.

My sincere thanks for the speedy fix.
