Comment 23 for bug 1970127

I'm experiencing quite exactly the same situation of Roxnny on a Hp ENVY x360 15-eu0000sl
I had booting troubles with 22.04.1 live usb and also with an installed 20.04 after a kernel update (5.15.0-46)

Anyway I managed to boot 22.04 live usb adding acpi=off parameter to boot options.
After installation and update of 22.04 I still can boot the system just if I add acpi=off
Unfortunately that brings some bad malfunctionings: I can't see battery level, touchpad doesn't work, and it seems from system monitor that just one cpu core is working.

A couple of further notes:
- during installation I had (twice) a grub install failure, I had to install it manually later
- sometimes firefox starts with just a black screen, I have to close it and launch it again
