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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1810546 Title: AMDGPU VMC page fault with Athlon 200GE APU To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1810546/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
