Needed to add these kernel flags to stop the display from locking up. Looks like PSR related issues.
On archlinux add them to /etc/kernel/cmdline and then update your bootloader and you can now enjoy your Zen5 machine on linux!
Hey, I think you forgot to add the flags (or they were deleted by moderators?). Did you use the ones from BNieuwenhuizen's excellent zenbook-s16 Github, or could you please add there here?
Thanks.
