I am seeing the same sort of bug on my machine. msi X470 motherboard (just tried latest firmware - no change) AMD Ryzen 5 2400G and Ubuntu 18.04 Linux paul-ubuntu 4.18.0-25-generic #26~18.04.1-Ubuntu SMP Thu Jun 27 07:28:31 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux Sometimes it happens overnight when machine is idle / screen locked, other times when using machine. Oddly enough the most recent one still had the mouse moving but keyboard unresponsive. Also a remote reboot fails - unless I use the watchdog with 'nowayout=1' to for a hard reset 60s after things should have gone down so it seem systemd won't/can't stop the hung graphics system. Typically the error messages look like:
[ 2567.463753] amdgpu 0000:27:00.0: [gfxhub] VMC page fault (src_id:0 ring:24 vmid:3 pasid:32770) [ 2567.463763] amdgpu 0000:27:00.0: at page 0x000000010be01000 from 27 [ 2567.463767] amdgpu 0000:27:00.0: VM_L2_PROTECTION_FAULT_STATUS:0x00301031 Often repeated many, many times. Seeing this bug report this has been going on for over a year now it seems and still is not fixed! Also a friend of mine is seeing the same on another AMD-based system. All pretty crap and makes me seriously regret buying an AMD board. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1810546 Title: AMDGPU VMC page fault with Athlon 200GE APU Status in Linux: Confirmed Status in linux package in Ubuntu: Confirmed Bug description: System - AMD Athlon 200GE - Gigabyte GA-B450M-S2H board - latest F2c Firmware - Ubuntu 18.04.1 LTS Reproducible with kernels - linux-image-generic-hwe-18.04 version 4.18.0.13.63 - linux-image-unsigned-4.20.0-042000rc4-generic_4.20.0-042000rc4.201812030528_amd64.deb --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.5 Architecture: amd64 DistroRelease: Ubuntu 18.04 InstallationDate: Installed on 2016-08-15 (872 days ago) InstallationMedia: Mythbuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) Package: linux (not installed) Tags: bionic Uname: Linux 4.20.0-042000rc4-generic x86_64 UnreportableReason: The running kernel is not an Ubuntu kernel UpgradeStatus: Upgraded to bionic on 2019-01-03 (1 days ago) UserGroups: _MarkForUpload: True --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: mythfe 2175 F.... mythfrontend.re mythfe 2181 F.... pulseaudio /dev/snd/pcmC0D3p: mythfe 2175 F...m mythfrontend.re DistroRelease: Ubuntu 18.04 HibernationDevice: RESUME=/dev/mythnew/swap InstallationDate: Installed on 2016-08-15 (872 days ago) InstallationMedia: Mythbuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) MachineType: Gigabyte Technology Co., Ltd.
