I have a Thinkpad e565, a Fury X, and a Fury Nano for testing amdgpu. However, I have nothing that uses Radeon. After all the time I've put in to Intel (continue to put in :-/) I feel that I would be remiss in simply tossing the code out there and hoping that it works.

I have amdgpu loading (and when I start dogfooding that will be the driver that gets all the use), but debugging it is taking a backseat to fixing support gaps in i915. A GCN1 system would actually be ideal as that's something that will only be supported by radeon - at least until the end of the year. > > Thanks. > > -M > > > > -- > > > > William A.

On further review, I think I have a close cousin, not this exact board. Mine is socket AM1 (socket), not FT3 (soldered onto the mbd). Otherwise very similar feature wise, has been rock solid for me (along w/ FreeBSD 9.3R :-) ).
