        <pre>Either you have a different problem than me (unlikely, as we have the exact
same symptoms), or you misunderstood my workaround. Or my workaround somehow
doesn't work for you. However, since you talk about actually upgrading the
firmware to a newer version, I'm guessing you didn't understand the workaround.

For my workaround, I neither upgraded nor downgraded any firmware version.
However, Linux 4.8 and Linux 4.9 try to load different files for the same
graphics card. Linux 4.8 loads tonga_smc.bin where as Linux 4.9 loads
tonga_k_smc.bin. Linux 4.8 fully works for me, including 3D acceleration, Linux
4.9 runs into the symptoms you described (black screen, fans running full
speed).

Now, if I replace tonga_k_smc.bin with tonga_smc.bin, then Linux 4.9 _also_
fully works for me, including 3D acceleration. That's without upgrading or
downgrading any firmware files. All I did was this:

cp /lib/firmware/amdgpu/tonga_smc.bin /lib/firmware/amdgpu/tonga_k_smc.bin

Here's the md5sum of all my Tonga firmware files:
fa6590cc9c9c1b2e7c92874fe98460fa  tonga_ce.bin
16bb427918581c29c2e910b5757a1b5b  tonga_k_smc.bin
73befe8abbaa7589d4e701ff77291e62  tonga_k_smc.bin.orig

1a81cffe8a10460b8ca9eaad537e7286  tonga_vce.bin

Note that tonga_k_smc.bin and tonga_smc.bin have the same md5sum on my system,
because I copied tonga_smc.bin to tonga_k_smc.bin to make Linux 4.9 work.</pre>
