This bugzilla has Keywords: Regression.  

Since no regressions are allowed between releases, 
it is also being proposed as a blocker for this release.  

Please resolve ASAP.

Patch to add sysctl version check for physinfo in kernel
Comment 10 Tetsu Yamamoto 2008-07-21 10:24:31 EDT
Interface version check between HV and userspace was modified in RHEL5.2
to allow through physinfo calls with newer versions for NUMA extensions.
 HV and tools have the modification, but kernel does not have it which
is needed for xen/ia64.  The attached patch on comment #9 adds it in kernel.
Comment 11 Daniel Berrange 2008-07-21 10:26:37 EDT
Ok, this isn't a userspace bug then - switching to kernel-xen instead.
Comment 12 Don Zickus 2008-07-25 16:26:46 EDT
in kernel-2.6.18-100.el5
You can download this test kernel from http://people.redhat.com/dzickus/el5
