https://bugzilla.kernel.org/show_bug.cgi?id=193341 Bug ID: 193341 Summary: AMDGPU: kernel NULL pointer dereferenced with hybrid graphics Product: Drivers Version: 2.5 Kernel Version: 4.9.6 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: stefan.kohek@xxxxx Regression: No Created attachment 253261 --> https://bugzilla.kernel.org/attachment.cgi?id=253261&action=edit Kernel config, output of dmesh (with stack trace), output of lspci The driver crashes when AMDGPU is used with a combination of R5 M230 and MULLINS. The driver work with MULLINS OK, when discrete GPU (01:00.0 R5 M230) is disabled (in bios). Kernel: Linux LenovoPC 4.9.6-1-ARCH #1 SMP PREEMPT Thu Jan 26 09:22:26 CET 2017 x86_64 GNU/Linux Relevant config: CONFIG_DRM_AMDGPU=m CONFIG_DRM_AMDGPU_SI=y CONFIG_DRM_AMDGPU_CIK=y CONFIG_DRM_AMDGPU_USERPTR=y I understand this is experimental case. Anyway, maybe somebody will fix it. This case work OK with RADEON driver (even offloading). -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
