It's not mangled per se, it's a panic message frome one CPU while the other CPU
was initializing. It looks like using a serial console exacerbated the race on
the kernel console output and ended up dropping characters. Of the
'SMP: AP CPU #1 Launched!' message you seem to have 'MP: CPU1 Launced!' with
'p/sbin/initaittic_initialize()' mixed in with it. Hmm, are you booting
verbose?
Hmm, a verbose boot on my dual 600 with a non-serial console has this:
SMP: AP CPU #1 Lstart_init: trying /sbin/init
uanched!
SMP: CPU1 apic_initialize():
...
So perhaps it is not panicing, but just the usual console mangling resulting
from multiple processors writing to the kernel console at the same time. I'm
not sure why it hangs for you though..
