2.6.16-10.2080.16.rdt.rhfc5.ccrmasmp but I tried the PREEMPT-RT kernel
    too with the same result. The boot process simply stops at (last
    line of output).

ide0: ports already in use, skipping probe

I doesn't throw any errors as far as I can see. The output up until the
point above is identical compared to the boot process with the single
CPU kernel.
