platform radeon_cp.0: firmware: radeon/R100_cp.bin will not be loaded
radeon_cp: Failed to load firmware "radeon/R100_cp.bin"

radeon 0000:01:00.0: failed initializing CP (-16).
radeon 0000:01:00.0: Disabling GPU acceleration
It worked fine with 3.0.0.
The firmware is compiled in to the kernel.
Doing bisects on this box is painful; it may be some time before I can do so.
