https://bugzilla.kernel.org/show_bug.cgi?id=217764 Bug ID: 217764 Summary: nouveau: system hangs when changing pstate on GeForce GT 320M (NVAF (MCP89)) Product: Drivers Version: 2.5 Hardware: i386 OS: Linux Status: NEW Severity: normal Priority: P3 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: dswdev@xxxxxxxxxxx Regression: No Created attachment 304780 --> https://bugzilla.kernel.org/attachment.cgi?id=304780&action=edit Crash log System hangs after pstate is changed with /sys/kernel/debug/dri/0/pstate interface to any option (like 0f). It hangs sometimes right after changing, and sometimes after few moments. According to kernel log it seems it attempts to divide by zero for some reason in gt215_clk_info (drivers/gpu/drm/nouveau/nvkm/subdev/clk/gt215.c) and fails with divide by zero interrupt which causes system to hang. It happens on MacbookPro7,1 (Macbook Pro 13 inch Mid 2010) with NVIDIA GeForce GT 320M on Fedora 38 with Linux version 6.4.7-200.fc38.x86_64. -- You may reply to this email to add a comment.
