Those are not really errors. On x86 one cannot attach to interrupts 2,
4 and 12 because they are already used. Attaching to all other
interrupts worked ok. Please also add "earlyprintk=yes" to the Linux
kernel command line to see more output and CONFIG_EARLY_PRINTK is
enabled in the L4Linux build. This should give more output.
