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 versi= on 6.4.7-200.fc38.x86_64. --=20 You may reply to this email to add a comment.
