Anything in particular you are doing when it hangs? Specific app?
I'm streaming via Steam in-home streaming and occasionally a fullscreen application will mess things up. When I reboot, SDDM/Plasma hang because of that driver crash. Leaving the up to date firmware files in there, it comes back after a couple reboots (randomly), and continues to work for a while. For now I have just downgraded back to my distro shipped linux-firmware. I'm not sure if the fullscreen issue is related but I know it definitely causes SDDM/Plasma init to freak out. So I'd say that's when it hangs the most for me.
Do you have similar issues with a newer kernel?
I will try from git and report back. As it turns out the reason I was having to reboot on some fullscreen games freezing was due to this same issue. Both games that were showing that behavior are now working on the older firmware.
Linux e55 4.18.0-rc5-g9ffc59d57228 #1 SMP PREEMPT Thu Jul 19 15:27:18 EDT 2018 x86_64 GNU/Linux Newly updated linux-firmware (18.20) log2.txt Booted fine, went to launch a fullscreen Wine game, threw the error. ---- Linux e55 4.18.0-rc5-g9ffc59d57228 #1 SMP PREEMPT Thu Jul 19 15:27:18 EDT 2018 x86_64 GNU/Linux Reverted linux-firmware log3.txt This time even after revert SDDM/Plasma failed to load and subsequent driver driver. I realized that the working state I was in was due to amdgpu.dc=0 and not the version of the firmware. Both of those logs are with amdgpu.dc=1 and exhibit the crash no matter the firmware version. I am currently booted into 18.20 firmware and amdgpu.dc=0 and everything is working.

Correction from above: This time even after revert SDDM/Plasma failed to load and subsequent driver crash.
Please change the bug title to reflect that it's related to DC, not firmware.
