Can you hook up a serial connection, and send the output during boot.

Subject: [Xen-users] Xen 4.0.1 kernel panic

 

Hi

Has anybody got an idea why xen 4.0.1 panics during boot?!
I have a Tyan server with 48 AMD cores and 128GB RAM. I compiled and installed xen 3.X along with CentOS 5.5 default xen kernel. Everything was OK there. The only problem I had was that CentOS kernel is allowed to see only 32 cores and 32GB of RAM which is actually supposed to be. However I wanted to see all cores and RAM in dom0, so I went for xen 4.0.1
This release of xen along with CentOS 5.5 default xen kernel work fine on my laptop which has a core2due Intel processor and 4GB RAM. But it does not work on Tyan server and I get kernel panic error (not syncing ...).
Any idea of what is this error for?!!

Regards
Mohammadi
