| Summary | X hang (in kernel) after some event in Serious Sam Fusion using radv. 4.9/and-staging-4.9 |
| Product | DRI |
| Version | DRI git |
| Hardware | x86-64 (AMD64) |
| OS | Linux (All) |
| Status | NEW |
| Severity | major |
| Priority | medium |
| Component | DRM/AMDgpu |
| Assignee | dri-devel@lists.freedesktop.org |
| Reporter | bugspam@moreofthesa.me.uk |
To reproduce, play Serious Sam Fusion (Vulkan rendering). X should freeze after a few minutes; at the start of SS:TFE, venturing out into the desert or killing an gnaar should be enough to trigger it. It looks like a fence + buffer object 'interaction'. This appears to affect all Linux 4.9.x and amd-staging-4.9; other kernels are as yet untested. Mesa 17.0.2 or git, libdrm 2.4.75, llvm 4.0~svn294803. Hardware is RX 470.
