Hello, I currently have the same problem with Kernel 5.15 when installing Ubuntu 22.04.
My laptop is an Hp ENVY x360 Convertible 15-eu0xxx.
I have secure boot disabled in the bios and I have been unable to install Ubuntu 22.04.
In version 20.04 a successful installation was made but it is not installed with the wireless network drivers.
If I try to update the kernel while it is in version 20.04 after the installation I start to have boot problems.
So far I haven't tried the installation again and I really hope that the problem will be solved as soon as possible.
