Hi Adrian,
Thank you again for these images.
I tested on Mac Mini G4 with 1MB RAM. The installation performed well. I
only installed and tested LXDE that is the one that works the most, in
my previous installation tests (in which I tried my favourite that is MATE).
- in Xorg.log, once, I had: "(EE) event1 - HID 04d9:048e: client bug:
event processing lagging behind by 79ms, your system is too slow".
- and another time:
[ 1652.968] (EE) RADEON(0): drmmode_do_crtc_dpms cannot get last vblank
counter
[ 66040.193] (EE) RADEON(0): drmmode_do_crtc_dpms cannot get last vblank
counter
[ 82060.115] (EE) RADEON(0): drmmode_do_crtc_dpms cannot get last vblank
counter
- some freezes during "apt upgrade"
- I had a problem with the boot partition on the installation of a newer
version of Linux kernel
- after some inactivity, the user login screen appears, and after having
logged, the desktop has corrupted errors (please find the dmesg log below).
- after several installations of packages and "apt update", I got:
"Warning: Skipping acquire of configured file 'main/source/Sources' as
repository 'http://deb.debian.org/debian-ports sid InRelease' does not
seem to provide it (sources.list entry misspelt?)"
- there is no GPU acceleration
- Some programs work: netsurf-gtk, LibreOffice Writer, VLC
- Some programs don't: glxinfo, darkplaces or scummvm (even running this
one with software renderer) that fail with the message "LLVM ERROR:
Relocation type not implemented yet!"
- Trying to install caja, I got the same error than with an image
provided last year: "Unsatisfied dependencies"
- I get an UBSAN trace in dmesg using a simple "perf stat" command ...
So, to summarize, the installation itself works well but I face some
known things with this venerable but old and limited machine: no GPU
acceleration, no Internet experience to expect, limited memory ...
I will see if I have time to install a ppc64 image on PowerMac this
week-end.

Hi,
I have created updated installation images for Debian Ports [1].
I have briefly tested the images on powerpc and sparc64. There was an
issue with debian-installer failing in the partioning step which was
caused by a dependency loop of the udebs. After removing the partman-*
dependencies from partman-hfs, the issue was resolved. I need to perform
further investigations to figure out why the problem didn't exist in the
past.
Anyway, please download and test the images and report back!

Here is the dmesg log obtained after we come back from the login screen
(not the initial one):
