[Bug 2141475] Re: 6.19 kernel fails to load, possibly because of nvidia configuration issue

Unfortunately, the 6.19 kernel still crashes on boot after I purge
nvidia drivers and re-install linux-image-generic and linux-
image-6.19.0-3-generic.

Title:
6.19 kernel fails to load, possibly because of nvidia configuration
issue

Status in linux package in Ubuntu:
Incomplete

Bug description:
On ubuntu 26.04, I upgraded to kernel 6.19 with nvidia-driver-590-open installed. I got configuration errors, and the 6.19 kernel failed to load.
After purging all the nvidia-related packages with sudo apt remove --purge '^nvidia-.*', no configuration errors remain, but the 6.19 kernel still crashes on load.
This issue appears with the nvidia-driver-580-open driver as well, so I think this is a kernel issue and not an nvidia issue.
Kernel 6.18 works fine with nvidia drivers.

This is what I get with each initramfs attempt when the nvidia driver
is installed:
