BenH advised to boot with udbg-immortal and out came: http://nerdbynature.de/bits/3.0-rc1/linux-3.0_powerpc_2.jpg http://nerdbynature.de/bits/3.0-rc1/linux-3.0_powerpc_2.mp4 (watch it at very slow speed, as it's only 3sec long) I've enabled[0] FB_NVIDIA and during normal booting the screen flickers after the "... : fixmap" message and the screen clears and is filled again from the top - maybe the messages would've been there if booted w/o the framebuffer enabled. Right now I'm happy that Ben's fix helped to get past this message, but the system remains unsuable[1] with the latest -git, but more debugging has to wait until tomorrow... Thanks, Christian.
