Hi Drake,
   I've rebuilt the kernel a couple of times since I sent the note
earlier but just saw the same failure again. Both times it occurred
when exiting mythfrontend.

Here are the modules I have been loading when using rt-sources-2.6.24-rt1

lightning ~ # cat /etc/modules.autoload.d/kernel-2.6
# /etc/modules.autoload.d/kernel-2.6:  kernel modules to load when system boots.

# Note that this file is for 2.6 kernels.

# Add the names of modules that you'd like to load when the system
# starts into this file, one per line.  Comments begin with # and

I do not see the radeon driver which is loaded under 2.6.24-rt1 so I'm
wondering where it ran off to. I also have two 1394 stacks loading.
I'll fix that next.

Sound isn't working under this kernel yet. Much to debug...

Thanks for looking at this.
