Hi all,
I've been trying to get a evergreen adapter to work with the Radeon driver on a ppc64 machine. And while attempting that, I'm running into what seems to be a infinite loop while running the IB test on ring 3. I'm using a 3.8.0-rc4 kernel from today. Follows an excerpt from the logs, the entire modprobe log can be found attached.

Do you guys have any idea what could be wrong, or what should be looked into?
Thanks
