hm, sounds interresting.

so this is supposed to replace "acpi_osi=Windows 2018.2" + acpi_backlight=vendor grub parameters when encountering freezes?

perhaps worth a try.

seems a little late though. according to the article's comments, kernel 5.4.7 saw a lot of patches making even this step superflous. so, no more parameters needed very soon? :slight_smile:

maybe lets see.
if it gets improvement or not.

also coming version 10bits HEVC

I tried replacing iommu=soft with amdgpu.noretry=0 and it froze.

again, good find.

this replaces all modifications that were necessary to fix those freezes, thanks!

With the latest testing update, which introduce kernel 5.4.10, my Athlon 220GE doesn't freeze anymore!! :clap::clap::clap:

Update: I think I spoked too soon, the system freezes again... :sweat_smile: Rolling back to 5.3.18.
