Hi Keir,
For me the current unstable tree is not working
with 8 cpu and SMP dom0 on a IA32 server. I found that this patch http://xenbits.xensource.com/xen-unstable.hg?cmd=changeset;node=a0b4156cc0ce4e6495cfa316c5383ee2be81c22f
has introduced some issue. I also see same issue if I pass maxcpus=4 option in
the hypervisor command line.
After reverting the patch, SMP dom0 can boot with 8 cpus
with the 6453 release from the xen-unstable.
I see these errors while booting the SMP dom0 kernel.
