The very newest Linux (git head, Debian unstable, ...) runs on it, most times better than older ones. > But it seems to be a little bit fragile.

But in fact, nobody really tests C8000 with graphics card. All c8000 machines I own run "server-like" in the datacenter. > I had to switch it off and after powering it up again it crashed > during the next booting.

I assume this is based on the fact that you used graphics before. > There are only a lot of "unaligned access" messages on the console > coming from KDE applications, but I guess, that's a known issue. Yes, they are non-critical and just show that applications don't respect the natural alignments of data. > I've taken a photo of the console with the backtrace after the crash, > but it doesn't seem to be possible to send a mail with an attachment.
