Bug#1033058: Booting mini.iso : kernel hangs on ppc64el



Ok found it...

oops! .. not that much to display though (I also tried to remove the
"quiet" boot option, but it didn't change anything, it does not display
anything before getting in debian's init)

From linux changelog (
https://tracker.debian.org/media/packages/l/linux/changelog-6.1.15-1 )
and http://snapshot.debian.org/package/linux/,
I see :
6.1.11-1 -> Bump ABI to 4 http://snapshot.debian.org/archive/debian/20230211T151657Z/
6.1.12-1 -> Bump ABI to 5 http://snapshot.debian.org/archive/debian/20230217T033139Z/

and tested from those (rebuilding the same d-i source with the 2 kernels
from snapshot.d.o . 6.1.12-1 clearly doesn't work.
I had already have a look at the kernel changelog but missed that one :
---
linux (6.1.12-1) unstable; urgency=medium
...
    - of: Make OF framebuffer device names unique
...
---

I recompiled the kernel deb source without that one (
https://github.com/torvalds/linux/commit/241d2fb56a18473af5f2ff0d512992a996eb64dd.patch
) and the mini.iso actually made it to the menu... and given the
behaviour, a framebuffer actually makes sense.

Now, that patch does not harm when the kernel is installed on disk.
But it does in the installer...
