Thanks for the reply, Alex. I had googled for those messages, too, and
had found that RCU info. Unfortunately, I have no idea what to do with
it, since it stops right at the booting stage, right before init starts,
so before I can do anything interactive.
I have posted a message to the LKML, maybe someone there has a hint.
(The machine is old and rarely used, but I would still like to run the
newest software because it is connected to the net.)
Peter.
