To be fair, amdgpu can be a dumpster fire at times...
I've also seen cases where I get that sdma ring buffer timeout, and rather than resetting the GPU, it spews garbage continuously in dmesg before I have to power cycle it.
On the other hand, that 2950x system is cursed. Half the time I boot it up, it downclocks the memory to 2400, won't detect USB devices... or part way through booting the kernel decides that it doesn't want anything to do with the pcie bus and panics.
