Comments/Problems:

This box has been running Debian for quite some time so I know it's
basically supported.

Issues:

* X (important)

The BIG problem is X. The installed lightdm starts the X-server which
fails to drive the display in a proper way. Instead it slowly turns
completely white, like oversaturation. I saw this phenomenon on some
PC style hardware many years ago but forgot how to deal with that.

X used to work in the past, at least in lenny, while it was broken
from jessie the latest. Since I don't need X on this machine and also
usually run my own kernel, I used to blame the latter und never
investigated.

The Xorg.0.log file is attached.

* network card (requires more checking)

There was a glitch with network card detection. Identification and
configuration worked well but afterwards the ethernet link was
flapping when starting network install. This misbehaviour disappeared
again without an understanding why.

* module loader

Some unidentified process inserted "apm_emu" into /etc/modules which
cannot be loaded as it's not available. Subsequently,
systemd-modules-load.service ends up in the "failed" state.

Regards,
    Christoph
