--- Comment #2 from jim.cromie at gmail.com ---
thank you Alex, the firmware page helped some.

Turns out I needed more than the CEDAR_smc.bin,
(which fwiw was never warned about)

[    1.756212] radeon 0000:01:00.0: radeon_uvd: Can't load firmware
"radeon/CYPRESS_uvd.bin"

which went away only after fetching that FW too.


So, having both FWs, I tested current master and it worked.
(I'll assume that means my bisect-bad would too)

Im a bit puzzled at the apparent need for 2 different CODENAME_ firmwares,
an also why theres no warning for missing CEDAR_smc.bin
