That's a good news for us!

Here I'm still using 2.6.11 xeno64 with your SMP patch, actually, it's
very stable with "init=/bin/bash", I can successfully run "find /" and

But once I run a process on cpu 1, it will crash the system.

bash-3.00# taskset 1 ls
bin   etc   lib         media  net   root     srv       tmp
boot  halt  lib64       misc   opt   sbin     sys       usr
dev   home  lost+found  mnt    proc  selinux  tftpboot  var
bash-3.00# taskset 2 ls
(XEN) Domain 0 (vcpu#1) crashed on cpu#1:

So, I think cpu 1 is not completely properly initialized for running
user applications.

BTW, when can you share us your SMP patch against 2.6.12?
