Patch to check for null drhd before use.v2
Patch checks drhd not only in msi_msg_read(write)_remap_rte but also in reassign_device_ownership.
in kernel-2.6.18-170.el5 You can download this test kernel from http://people.redhat.com/dzickus/el5 Please do NOT transition this bugzilla state to VERIFIED until our QE team has sent specific instructions indicating when to do so. However feel free to provide a comment indicating that this fix has been verified. system fails to boot with kernel-xen 2.6.18-164.11.1.el5 system booted correctly with kernel-xen 2.6.18-192.el5 In both cases I modified the kernel line in grub and added "noacpi acpi=off" parameter. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA.
