The capabilities kernel is the original redhat kernel plus the
capabilities patch (which enables you to run jack as a normal non-root
user). It has a partial low latency patch that is better than nothing
but does not provide the best possible performance.

That would be difficult because the full latency/preemptible kernel
patch conficts with other (complex) patches that redhat applied to their

My guess is that the ccrma kernel is detecting the drives in a different
order and/or naming them differently than the original redhat kernel
that was used to install fc1. 

Exactly what drives do you currently have attached to the system? On
which one do you have fc1 installed? Also, if you have multiple installs
and/or multiple drives it may be possible to confuse the boot process
(depending on how the installs were done). 

Could you send a few more lines before the point where the system hangs?
