Does the booting kernel unload the radeon driver prior to switching to the
resuming kernel?  If not, the resuming kernel may take over before the radeon
driver has finished loading in the boot kernel, or in the middle of some
operation which leaves the GPU in a bad state when the resuming kernel takes
over.
