Description Jon Masters 2008-11-21 03:54:17 EST
Description of problem:

In RHEL5.2, the virtualization team shipped a version of the "HVM" drivers to allow full-virt guests to have accelerated hardware access. These drivers were supplied using a Driver Update package, which is to be deprecated in RHEL5.3.

Additionally to deprecating these external modules and supplying a replacement directly in the RHEL5.3 kernel, the kernel configuration was also changed. This change results in one of the modules being built directly into the kernel, rather than having all built as external loadable entities. As a direct consequence, module dependencies are misgenerated whenever a system has the existing external drivers installed alongside the 5.3 kernel.

The fix is to build the RHEL5.3 kernel with the modules external rather than directly built into the kernel. The fix has been tested and should be considered as a matter of urgency for the 5.3 kernel.
