I am running on x86_64 hardware, but running it in 32 bit mode, i.e., all the software and the Linux (Suse Sles 9) is in 32 bit.

The box has two Intel Xeon EMT64 procs with hyperthreading enabled with 2 Gigs of RAM. I find that when I install and run xen (the unstable build ChangeSet: Sat Jul 16 12:45:24 2005 722c372fe2017414acd568874a313a8f5e8685f5) the system crashes on Dom0 boot.
I am running the 2.6.11 kernel for Dom0

Here is the relevant dump, from the serial output.
At this point, I tried to attach gdb, but without success.

You need to run a matched dom0. Older dom0's (like your 2.6.11 must be) will not work.

We don;t keep backward compatibility in the unstable tree, only during stable series.
