Hi, Running xen-devel with the fedora-devel kernel on a Athlon XP results in the following panic for xenU guests. Strangely, xen0 boots up fine and runs without any problems. Additionally, the same kernel binary was tested on a system running an Intel Pentium-M and it works fine. Any ideas or anything else I can do to help?

I''ll check in a fix to the unstable repository. -- Keir ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.

Have you added any kernel patches to the kernel from fedora-devel? -- Robin ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.

One contributing factor may be that the CPU is an Barton Core XP Mobile. I will take a look at it and see what I could find. ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
