Synopsis: Minecraft causes the entire system to hang Category: system kernel amd64
I was playing Minecraft on a machine with a R7 360. Whenever I join a server, after a few minutes or almost immediately, the entire system begins to hang and stop responding. On a few occasions I can see this message being spammed. [drm] *ERROR* Couldn't update BO_VA (-22) drm:pid1773:radeon_sync_rings *ERROR* Syncing to a disabled ring!drm:pid1773:radeon_ib_schedule *ERROR* failed to sync rings (-22) This occurs on all Minecraft version, and on all radeon_firmware versions from 6.6 release to 6.7 beta. Once this occurs, the system require a hard shut down. It won't respond to ACPI signal. Similar problem also occur for amdgpu from 6.6 release to 6.7 beta, but with a different error message: [drm] *ERROR* ring gfx timeout, signalled seq=10088, emitted seq=10090 When this happens on amdgpu, it responds to ACPI signal, so I can still gracefully shut it down by pressing the power button. The problem only seems to happen when I'm playing on a server where there are a lot of activities. On an empty world I haven't encountered this problem before. I suspect the amount of activities lead to a huge amount of OpenGL calls and that somehow screw up the system. I am willing to share a Minecraft account to reproduce this problem. Thank you for your help.
