when booting into fedora 36 with my hp victus 15 gaming laptop, the brightness doesn't work and the computer is stuck on dim. On dmesg the output reads:

[ 0.229652] ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PCI0.28**.EC0], AE_NOT_FOUND (20220331/dswload2-162)

Hi,

I do have very similar ACPI error messages (see this thread: HW - Laptop PC 'LG Gram 16Z90Q' - ACPI trouble + CPU Crazy HOT !, But, everything relted to brightness seems working fine, so far, for me.

I did Not find yet anything much about this "AE_NOT_FOUND" issue, that's why I joined Linux.org comunity, this time.

Just being currious what's your hardware and do you have a crazy hot CPU ?


Best regards,
HP
