https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=250503 Bug ID: 250503 Summary: [panic] OpenGL operations with radeon hardware Product: Base System Version: 12.1-STABLE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: pr@aoek.com Hi, I get a number of panics with any OpenGL operation on Radeon hardware. Stack trace includes radeon_crtc_handle_flip() or radeon_sa_bo_new(). I have photos of the panics if useful. How to reproduce: vblank_mode=0 glxgears Or any other GL consumer. I am unable to obtain a kernel dump on panic, despite having dumpon configured and kern.coredump=1, as the machine is completely hung (long press power button to switch off). % uname -a FreeBSD radeon 12.2-STABLE FreeBSD 12.2-STABLE GENERIC amd64 svn #366230 Was OK in previous versions (12.1 STABLE), cannot dissect which one exactly. In July it was working. % pkg info|fgrep drm drm-fbsd12.0-kmod-4.16.g20200221 DRM modules for the linuxkpi-based KMS components libdrm-2.4.102,1 Userspace interface to kernel Direct Rendering Module services % pkg info | fgrep -i opengl glew-2.2.0 OpenGL Extension Wrangler Library libGLU-9.0.1 OpenGL utility library libepoxy-1.5.4 Library to handle OpenGL function pointer management libgltf-0.0.2_21 C++ Library for rendering OpenGL models stored in glTF format mesa-demos-8.4.0_2 OpenGL demos distributed with Mesa mesa-dri-20.2.0_1 OpenGL hardware acceleration drivers for DRI2+ mesa-libs-20.2.0_1 OpenGL libraries that support GLX and EGL clients qt5-opengl-5.15.0 Qt 5-compatible OpenGL support module % pciconf -lv [...] vgapci0@pci0:1:5:0: class=0x030000 card=0x1609103c chip=0x97121002 rev=0x00 hdr=0x00 vendor = 'Advanced Micro Devices, Inc.

Is there a fix for this? Thank you. -- You are receiving this mail because: You are the assignee for the bug.help
