    I finally had the opportunity to reboot this system again.

    CONFIG_SLUB_DEBUG=y was set, so I tried adding slub_debug to the commandline.

    With slub_debug added the system boots normal, I could not see any
    errors in the syslog. When I remove slub_debug it crashed againb
    before reaching userspace.

    After the KMS fixes from Alex Deucher vanilla kernel 2.6.35-rc6 works
    for me. So I would thing my problems with earlier 2.6.35-rcs where
    just these KMS errors and this kmalloc problem has already been fixed
    in mainline.

    So I have switched this system to 2.6.35-rc6 and will stay with this kernel.

    Thanks, Torsten
