I have tried Xen 3.0.0 and 3.0.1 with 2.6.15 and 2.6.16rc1 from the hg
repository. The 2.6.16rc1 kernel crashes Xen itself. 2.6.15 gets much
further before dying. 2.6.12.6 boots fine.
Here''s a boot log. I notice an invalid opcode ... do I need to use a
particular version of gcc? I can provide .config, syms, etc., if desired.

Re: [Xen-users] Xen 3.0.1+Linux 2.6.15 goes kaboom. Help?
I tried gcc 4.0.2 with the same results. Then I added the "nosmp" parameter to the Xen kernel, and it boots fine, but with only one CPU! Any suggestions? Thanks!

Re: [Xen-users] Xen 3.0.1+Linux 2.6.15 goes kaboom. Help?
More data points: I can boot Xen with SMP, and a dom0 kernel with ''nosmp'' and it works. I can then start a domU kernel with ''nosmp'' on cpu1 and it works, but if I try to start an SMP-enabled domU kernel, it dies with the same error. I have been playing with kernel config options, so far to no avail. I tried to enable cpu hotplug support, but the final kernel link fails due to a missing symbol.
