Hello Tony,

Can you please open a Red Hat support case. We will be able to support
you better from that channel. Please point them to this discussion when
you do open a case.

There have been several changes between 2.6.18-164.el5 and
2.6.18-371.8.el5 kernels. Maybe you could try installing the
intermediate versions and try to determine where the changes took place.

Can you also expand on the following statement.

Can you show the outputs from both the working kernel and the newer
kernel which doesn't seem to work properly. I can use this to create a
reproducer on my test machines.
