DomU crash during migration when suspending source domain
Just run into an odd DomU crash doing live migration of a 4-VCPU domain (with 3.0.4 but the code looks the same in 2.6.18/unstable to me) - the actual panic is attached at the end of this, but the bottom line is that the code in cache_remove_shared_cpu_map (in arch/i385/kernel/cpu/intel_cacheinfo.c) is attempting to clean up the cache info for a processor that does not yet have this info setup - the code is dereferencing a pointer in the cpuid4_info[] array and looking at the dump I can see that this is NULL.
My working theory here is that we attempted the migration waaay early and the ini...
