Chester, could you recommit the changes, but now to master branch, so that it does not get lost on the next merge?

Comment 2 Macpaul Lin 2024-04-17 08:49:37 UTC

Created attachment 874330 [details]
config patch to master branch

Comment 3 Jiri Slaby 2024-04-18 06:16:29 UTC

Pushed to master and stable. Thanks.

Comment 4 Macpaul Lin 2024-04-25 07:23:47 UTC

Remind for users:

This extra kernel command line parameter is required for openSUSE installer (in grub).
'loglevel=8 module_blacklist=mediatek_drm,arm_dsu_pmu switch_to_fb=0'

The solution has been verified with

https://download.opensuse.org/ports/aarch64/tumbleweed/iso/openSUSE-Tumbleweed-DVD-aarch64-Snapshot20240423-Media.iso

kernel 6.8.7-1-default.

Thanks!
