[Bug 2038512] Re: [Mediatek] mt8195-demo: please help to include these MediaTek drivers in initrd.img in CD/DVD release image

[Macpaul Lin]

The setting of /etc/initramfs-tools/initramfs.conf was already set to
'MODULES=most'.

But it seems just not working for adding some of these drivers.
I was trying to configure these drivers on...

[Ubuntu Version]
Jammy

[initramfs-tools]
0.140ubuntu13.4

[Kernel version]
5.15 -> 6.2
(Generate initrd.img-6.2.0 on 5.15 kernel.)


** Description changed:

  [Impact]
  Peripheral probe failure for MediaTek boards 'mt8195-demo' and 'genio-1200-evk'.

  [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.
