Created attachment 138344 [details] dmesg, killing pids, shutting down, unloading amdgpu, xorg log WHAT HAPPENS - Amdgpu hangs without any clear clue of what is happening. - The mouse cursor responds to movements when the system is not frozen, but also it does nothing as well. - The keyboard gets num lock frozen and even trying with a ps2 one does not work. - The video gets frozen. - Only ssh works, but only the times that the system is not frozen, of course. - The most irritating part : the system can not be shutdown. No matter what you do : -- If you press the power button from the case, it is the only answer that you can get from the output display : it shows a console indicating that x-server is trying to be turned off. But nothing else happens and the system can't be turned off. -- If you try anything from ssh : "init 0", "poweroff", "shutdown -P 0 -h", "reboot". It simply does not work. It keeps waiting for something that never happens. Then you have to press ctrl_c to get back to the ssh sessioon. In an attempt it closed the ssh daemon but the shutdown itself never happened... even after 30mins. -- It is IMPOSSIBLE to force unload amdgpu using "rmmod -f amdgpu". The task takes forever and never responds. It only hangs the ssh session. -- It is IMPOSSIBLE to kill some x-related pids properly. If you try to kill it either nothing will happen or the process will be in a defunct state. Not even a "su -c 'kill -9 <pid>'" will work. TIPS - The crashes that allows ssh connection almost always happens when firefox is openned and running a video (netflix, youtube) or whatsapp web. - The crashes that simply hangs the entire computer may occur at any time. OBSERVATIONS - I use a custom kernel (from 4.15). I've tried including the polaris binaries for my card, that showed an improvement (less freeze states) for a while. But now it is the same again. - I use a nvidia io second pci-e slot for vfio. It is a must and I disable nouveau as well... It shoud not be a reason for failing. I tried also with another amd/none-card on second slot. The results were the same as I remember. SYSTEM SPECS - Custom kernel compilation optimized for ryzen (https://wiki.gentoo.org/wiki/Ryzen) and using polaris binaries (https://wiki.gentoo.org/wiki/AMDGPU) - Chipset X370 (mobo) - RX480 in first slot - GTX 1070 on second slot. - Tried also with a RX 580 on second slot. - Tried also with nothing on second slot. - i3wm loading from startx command
