In the past, RHEL Redhat has broken both API and ABI kernel interfaces
but kept the major.minor kernel and RHEL number the same. While they did it
for good reasons, hardware that is not supported out of the box
can break and you might have weeks or months to wait for a driver
update. RHEL is full of backports and other patches-- your hardware vendor needs to
stay dialed in and your site needs to double check updates as they surface
in the "test" area.
