I think these are just informational. I find this about psyco.

Psyco is unmaintained and dead. Please look at PyPy for the
state-of-the-art in JIT compilers for Python.

This seems to be your problem. Since radeon is a kernel module, it
is
possible that it is a kernel issue. What happens if you boot a
previous kernel?
If a previous kernel works, you should open a ticket against the
kernel
at
https://bugzilla.redhat.com/ describing your problem with the
radeon
driver.
If it doesn't, then something else has changed. That will take
further
sleuthing to find.
Ok, I tried the previous kernel, and had no luck.
I just remembered that I attempted to delete a package from my system
and it started to erase things, but I stopped it. This may have done
the damage. This was a real screw-up on my part, and so I don't think
a bugzilla is the correct action.
It had also erased the Repetier host package that I used to generate
the Gcodes for my K8200 printer. I reinstalled Repetier host and that
works, but pycam still does not. Nothing else seems to be affected.
However if the Kernel is the location, is the radeon package in a
separate file? If it is, what could I reinstall to recover that
driver?
