Yes, this patch will fix also RHEL5.2 because the base is 3.1.2. https://www.redhat.com/archives/rhelv5-list/2008-March/msg00111.html The bug may be occurred by changing __XEN_VIRT_START. http://xenbits.xensource.com/xen-3.1-testing.hg?rev/a06a28ebad5d So we may be able to fix it by changing DIRECTMAP_VIRT_START. I didn't have x86_64 system. I'll setup x86_64 system, and try to investigate it next week. Best Regards, Akio Takebe
