This sounds more like a gpu crash, or a deadlock in the xserver. So, I
don't think that these two cases are the same. Since you can ssh in,
have a look at top while it's hung and see what state the xorg process
is in. If it is in drmlk2, it's locked. If that looks ok, then it's
probably a gpu crash, if you set sysctl hw.dri.0.debug=1 you will
probably see a lot of radeon_cp_idle and timeout calls.
