I would like to note that is error spontaneously resolved after reinstalling. maybe something happened during installation, or my ISO was dirty.

Hello, for me appear also on 21.10, kernel version 5.15.11-051511-generic.

Status changed to 'Confirmed' because the bug affects multiple users.

I have this issue as well on a Dell XFR booting from a CD made by Cubic. I did find if I used the kernel that came with the disk (5.11.0-27 vs 5.11.0-48) it would boot and allow install.

same issue on Dell XPS 15-i9. using kernel 5.13.0-28-generic.

These three errors appear in dmesg, usually in succession.
