Title:
[Mediatek] mt8195-demo: please help to include these MediaTek drivers
in initrd.img in CD/DVD release image
Status in linux package in Ubuntu:
Incomplete
Bug description:
[Impact]
Peripheral probe failure for MediaTek boards 'mt8195-demo' and
'genio-1200-evk'.
[Kernel version]
6.2
[Fix]
I've used 'dracut' to examing the driver dependencies for boards
'mt8195-demo' and 'genio-1200-evk'.
It is able to buot into console and use USB port3.
Hope these drivers could help to run installer with USB disk in next daily
build.
Note: It won't work with 'update-initramfs -u -k 6.2.0-34-generic' if
just simply add driver lists in '/etc/modules',
'/etc/modprobe.d/mediatek.conf' or '/etc/modules-
load.d/mediatek.conf'. I fixed this issue with 'dracut' and it seems
this tool will include more common framework drivers into initrd.img.
