Ricky, Jean just went into his well-deserved weekend, but he told me to tell you that he has tried your boot disk, and has been able to reproduce your problem. He got it to run by replacing your Fiasco binary with a newer version of Fiasco. So you are probably using an outdated version of the kernel. You should download a newer version from our remote-CVS server (see <URL:http://os.inf.tu-dresden.de/drops/download.html for instructions).

Would it be possible to gzip the boot disk and send it to us? Then we could try to boot it and see, what fails. I´m not quite sure that I understand the scenario good enough to come up with an explanation and a fix. Somehow the service thread (5.3) touches a page in the adapter area (a0000-100000) and doesn´t get or doesn´t have a mapping for it. Jean -- I get up each morning, gather my wits.

Plaese .. Could you help me ?

Hi, everyone ! First of all, let me introduce myself . My name is Ricky Lee . I'm in the course of master's degree at Seoul National University in Korea. Thesedays I'm reading L4-related papers. And, I'm trying to make experience on L4Linux on Fiasco. But, It is not so easy for me. Today, I finally succeeded in building linux22. I really appreciate Michael Hohmuth' advices. But, I have another problem. When I boot from the grub floppy disk with glinux.gz on it, after the message that is saying the first task is created, the kernel fall into the endless loop with printing out " root: rcvd b9002, 4bc10c, src :5.3 ". I guess that it is printed out from root_pager() in l4_paper.c Can you tell me what's wrong ? And, then, what should I do? I really need to solve this problem. So, I really need your help. Please, Help me .. Thanks for your kindness . Thanks . P.S. I compiled Fiasco and Linux22 server on the Redhat package 5.2. Its kernel version is 2.0.36. Any software requirement that is mentioned in the L4linux homepage was met, I think . Can there be the reason of problem with the linux environment in which I compiled those sources ? Can anyone tell me the kernel version and H/W spec. on which you've built the L4Linux22 Server ? It'll be very helpful to me if you tell me them .. Please !!! Thank you very much !! - Ricky Lee -
