You may want to check the release notes for the kernel. I know they

keeping track; but, I believe there may be an issue with using the SMP
kernel with a P4.
I usually think SMP works better with multiple CPUs. HyperThreading
is really a trick more than multiple CPUs.
I did see something in the notes about changes to ACPI, but I can't
seem to find anything specific that indicates anything that addresses
issues with HyperThreaded P4s. Anyone have a link to notes that
discuss this?
I suggest that you file a bug report with redhat bugzilla. Someone
should take a closer look at this, especially if it is kernel related.
Which it may not be but one must find out. It could be udev related for
example.
