Where do I find more information about linux ACPI errors ?

[limestone_bob]

Hi,

Occasionaly my system freezes and the error log shows an ACPI error. Is there more information on the ACPI error?

I'm sorry, but we here are not equipped to provide detailed Linux support.

HP only warranties their PCs for usage with the OS that comes preinstalled. IF you replace that with Linux, or add a Linux OS, then you assume full responsibility for maintaining that -- as HP provides Linux assistance only on Redhat and then only to commercial customers.

The primary "challenge" to using Linux on any HP PC is the availability of Linux drivers. Any hardware that does not work will then range from simple (if there are Linux drivers available) to impossible (if there are NO Linux drivers available) to fix.

Since HP does not provide Linux drivers, your best bet for Linux support is to contact the support forum for the Linux distro you are using.

Thanks for response.

Where does HP post known issues or technical bulletins for their hardware that is running Redhat?

Hello,

I own a similar hardware HP ENVY x360 Convertible 15-cp0xxx running on Fedora 31 with similar problem. The good news is the fix related ACPI Error landed on Linux kernel 5.4.2 and stable kernel 5.3.15.

You can view the bugzilla report on https://bugzilla.redhat.com/show_bug.cgi?id=1520703

Yes, I updated to kernel 5.3 on Ubuntu and now the touch screen is working. I haven't been using kernel long enough to know if the occasional OS freeze has been resolved.
