That's sort of normal -- we probably should remove this message from

This probably is a kernel bug.  Fiasco does a read at an invalid
virtual address.  If you boot with the "-nokdb" kernel option, you
should be able to get a register dump even even if you don't have
connected a remote Gdb.  This, together with the output of 
"nm main | sort", could give you a hint about the reason of the crash.

I don't think the version of `init' makes a difference here.  However,
I will send you the version details soon.  Right now I can't check
because my test machine is busy this week doing benchmarks... :-(  Is
anyone willing to donate another test machine?
