There is a fix in git that I think that is for this bug too.
Check if the version of libdrm is 2.4.49.
If it is, the bug is probably the same.
Try the patch I'm sending.
The commit of the patch is:

http://cgit.freedesktop.org/mesa/drm/commit/?id=c8a437f4c76527b3c8385699ccee07f35fe3f166

I had this bug and this patch fixed it to me.

To help, I'm attaching the PKGBUILD and COPYING files to build the package.
Put the 3 files (the patch too of course) in a directory and run makepkg.
Install the new package.

Yes, this single-line-change radeon/radeon_surface.c fixes it. I have to add, that I tested another GPU (PITCAIRN) and the freezes also arise with the original libdrm-2.4.49-1.

Please try libdrm-2.4.50

libdrm-2.4.50 seems to work (tested with blender).
