It happened when switching window to Firefox. For me it only crashed Xorg, ssh to the machine still worked ok. Killing Xorg didn't work and `shutdown -r now` hung up somewhere. Here is a bug report on the Ubuntu package: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1881134 Here is call trace decoded with the debug symbols: -- [455834.385061] Call Trace: [455834.385120] mode_support_and_system_configuration (/build/linux-FFoizL/linux-5.4.0/drivers/gpu/drm/amd/amdgpu/../display/dc/calcs/dcn_calc_auto.c:176) amdgpu [455834.385174] ? calculate_inits_and_adj_vp (/build/linux-FFoizL/linux-5.4.0/drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_resource.c:950 (discriminator 12)) amdgpu [455834.385230] dcn_validate_bandwidth (/build/linux-FFoizL/linux-5.4.0/drivers/gpu/drm/amd/amdgpu/../display/dc/calcs/dcn_calcs.c:1034) amdgpu [455834.385283] dc_validate_global_state (/build/linux-FFoizL/linux-5.4.0/drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_resource.c:2093) amdgpu [455834.385338] amdgpu_dm_atomic_check (/build/linux-FFoizL/linux-5.4.0/drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:7413) amdgpu [455834.385351] drm_atomic_check_only (/build/linux-FFoizL/linux-5.4.0/drivers/gpu/drm/drm_atomic.c:1179) drm [455834.385361] drm_atomic_commit (/build/linux-FFoizL/linux-5.4.0/drivers/gpu/drm/drm_atomic.c:1220) drm [455834.385370] drm_mode_obj_set_property_ioctl (/build/linux-FFoizL/linux-5.4.0/drivers/gpu/drm/drm_mode_object.c:496 /build/linux-FFoizL/linux-5.4.0/drivers/gpu/drm/drm_mode_object.c:533) drm [455834.385379] ? drm_mode_obj_find_prop_id (/build/linux-FFoizL/linux-5.4.0/drivers/gpu/drm/drm_mode_object.c:512) drm [455834.385386] drm_ioctl_kernel (/build/linux-FFoizL/linux-5.4.0/drivers/gpu/drm/drm_ioctl.c:793) drm [455834.385394] drm_ioctl (/build/linux-FFoizL/linux-5.4.0/include/linux/thread_info.h:119 /build/linux-FFoizL/linux-5.4.0/include/linux/thread_info.h:152 /build/linux-FFoizL/linux-5.4.0/include/linux/uaccess.h:151 /build/linux-FFoizL/linux-5.4.0/drivers/gpu/drm/drm_ioctl.c:888) drm [455834.385402] ? drm_mode_obj_find_prop_id (/build/linux-FFoizL/linux-5.4.0/drivers/gpu/drm/drm_mode_object.c:512) drm [455834.385406] ? recalc_sigpending (/build/linux-FFoizL/linux-5.4.0/kernel/signal.c:184) [455834.385440] amdgpu_drm_ioctl (/build/linux-FFoizL/linux-5.4.0/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c:1293) amdgpu [455834.385443] do_vfs_ioctl (/build/linux-FFoizL/linux-5.4.0/fs/ioctl.c:47 /build/linux-FFoizL/linux-5.4.0/fs/ioctl.c:510 /build/linux-FFoizL/linux-5.4.0/fs/ioctl.c:697) [455834.385444] ? recalc_sigpending (/build/linux-FFoizL/linux-5.4.0/kernel/signal.c:184) [455834.385446] ? _copy_from_user (/build/linux-FFoizL/linux-5.4.0/arch/x86/include/asm/uaccess_64.h:46 /build/linux-FFoizL/linux-5.4.0/arch/x86/include/asm/uaccess_64.h:71 /build/linux-FFoizL/linux-5.4.0/lib/usercopy.c:14) [455834.385448] ksys_ioctl (/build/linux-FFoizL/linux-5.4.0/include/linux/file.h:43 /build/linux-FFoizL/linux-5.4.0/fs/ioctl.c:715) [455834.385449] __x64_sys_ioctl (/build/linux-FFoizL/linux-5.4.0/fs/ioctl.c:719) [455834.385451] do_syscall_64 (/build/linux-FFoizL/linux-5.4.0/arch/x86/entry/common.c:290) [455834.385455] entry_SYSCALL_64_after_hwframe (/build/linux-FFoizL/linux-5.4.0/arch/x86/entry/entry_64.S:184) [455834.385456] RIP: 0033:0x7faf3181837b -- 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
