There are a couple of things you could try out on Fedora 8...

a) install the newest Planet CCRMA 2.6.23 kernel, just released today.
It includes a newer version of the realtime preemption patch but I would
not have too much hope it will solve the problems...

b) install an _old_ kernel version based on 2.6.22 that I just released
for f8 (same kernel that I have released for f7). That is a bit tricky
because yum does not allow by default to "downgrade" packages, including
the kernel. You will need to:

- yum install yum-allowdowngrade

and then:

- yum install kernel-rt-2.6.22.10 --allow-downgrade

Good luck!
