Hi,
while trying to upgrade from 3.4.0 to 3.5.0-rc5 on this Powerbook G4 (powerpc 32 bit), this happens during booting:

This is what netconsole was able to receive. I've made a screenshot from another boot with the same vanilla 3.5.0-rc5 (today's mainline) and put it (along with some more details) up here:

Any ideas?
Thanks, Christian. -- BOFH excuse #436:
