This is related to your BIOS or motherboard. Do you have the same
problem with a vanilla 2.6.29?
I have not tested with vanilla 2.6.29 but the
problem happens in several
very different machines. I have sent feedback to lkml/Thomas/Ingo.

Strange. Then it might be one of the additional Fedora patches that is
triggering a problem in rt (the Planet CCRMA rt kernel tries to be as
close as possible to a production Fedora kernel so it keeps mostly the
same configuration and patches - this one is based on an unreleased Koji
test build).

Can you upload your .config ? It might also be some missing ACPI option. - using x86 generic compatibility dramatically

Thanks for the feedback!

Working wonderfully.
Delta 44 down to 2ms, Intel HDA to 8. No compensations made either, this is
a full-featured mobile workstation with suspension, dynamic frequency
scaling, and everything else working as well. No extensive patching/tweaking
of kernel options - just the essentials.
I believe this is not only an improvement with RT, but the Linux kernel has
also improved greatly over the past 3 years.
