Yes I have. My newest pursue is that Arch might have not picked up on all of the reverts of yours, as commented in my thread. I checked checksums and they didn’t match. I downloaded it manually, applied and I’m in the middle of testing now.
Edit: FWIW I think that pointing out expected FW version would be more descriptive for whoever struggles with it. When I found out that there’s 0x80 vs 0x83 it kinda became clear that something’s wrong.
$ cat /sys/class/drm/card1/device/fw_version/mes_fw_version
0x00000080
