Impossible to boot without losing functionality on HP Pavilion x360 a200nt

English Install/Boot/Login

Hello.

This is rather complex. As explained in https://bugzilla.kernel.org/show_bug.cgi?id=205237 my system was needing “acpi_osi=” being passed to kernel to boot. Sometime in Kernel 5.8 it required “acpi_osi=!” argument and in 5.9 era it required no argument being given.

Now on current 5.9.1-2 I can’t boot at all without passing acpi=off to kernel which makes bluetooth, wireless usb all disabled. I am using my phone’s USB tethering to have Internet. HP pretty much abandoned this model so there isn’t any new firmware. I am stuck in F.41 version.

I can’t use the OS in this state but keeping it installed just to report this issue. BTW I also tried 5.10.rc3 kernel which didn’t make difference.

Have you filed a bug report on this?

The kernel maintainers probably aren’t reading your posts. Filing a bug report is the way to get their attention.

I had serious issues logging in to bugzilla but created another account so yes, bug report is there 1178747 – Kernel now needs acpi=off to load on HP Pavillion x360 a200nt 13 inch

I had to reinstall openSUSE from a 10 day old image and upgraded to current, issue resolved itself. Now can boot with acpi_osi=! argument fine. It is likely the firmware doing this and there is little Linux devs/maintainers can do.
