Thanks for the reply, Alex. I had googled for those messages, too, and |
16 |
had found that RCU info. Unfortunately, I have no idea what to do with |
17 |
it, since it stops right at the booting stage, right before init starts, |
18 |
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 |
22 |
newest software because it is connected to the net.) |
