on bug 110822
from Matt Coffin
I'm experiencing the same problem, but with an XFX RX 590 FATBOY. Strangely enough, I am also running crappy, kinda slow DDR3 RAM at 1600 mhz. I've read so much on this issue today that I don't know where I read it, but I read somewhere that crappy RAM can cause these kinds of hangs with these cards. Is there some issue with running the GPU mclk faster than your system's RAM? My issue does not happen on boot, and does not happen until the GPU is under load, but occasionally (seemingly non-deterministically), I see the powerplay errors on startup, but amdgpu continues to load (seemingly OK) until I put it under heavy load. Do you have a mobo/cpu/ram setup with faster memory that you might be able to test with? I don't know too much about amdgpu internals but given what I read it seems odd that we are both running what would be considered "slow" RAM these days. My specs: * Kernel 5.1.3-arch2-1-ARCH * LLVM 8.0.0 * Mesa 19.0.4 * Card XFX Radeon RX 590 OC+ FATBOY * CPU: i7 990x extreme edition Interestingly, I had to set up fancontrol to get the fans to spin up past their minimum values at all, but I suspect that could be due to the usage of the "stealth" RX 590 VBIOS. Unfortunately, i don't have access to a windows machine to flash to "performance" bios on to my card, or even to check which version is in use currently. Let me know if I can help out with any logs/debugging information.
