https://bugzilla.kernel.org/show_bug.cgi?id=208913 Bug ID: 208913 Summary: amdgpu: RIP: 0010:amdgpu_dm_atomic_commit_tail+0x1cce/0x1de0 Product: Drivers Version: 2.5 Kernel Version: 5.4.58 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: alexander@xxxxxxx Regression: No Created attachment 290913 --> https://bugzilla.kernel.org/attachment.cgi?id=290913&action=edit dmesg I'm using 5.4.x kernels for quite some time. And recently X server started to hang sometimes after switching users. It starts using 100% CPU and killing it with sigkill is the only thing I can do. I'm using GNOME, so each user has its own X server. I believe this is caused by the following patch that was included in 5.4.56: "drm/amd/display: Clear dm_state for fast updates" But since the issue is not 100% reproducible, I need some time to confirm it. >From dmesg: [99448.103350] [drm:drm_atomic_helper_wait_for_dependencies] *ERROR* [CRTC:47:crtc-0] flip_done timed out [99458.343984] [drm:drm_atomic_helper_wait_for_dependencies] *ERROR* [PLANE:45:plane-5] flip_done timed out [99458.353716] ------------[ cut here ]------------ [99458.358491] WARNING: CPU: 1 PID: 2240 at drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:5883 amdgpu_dm_atomic_commit_tail+0x1cce/0x1de0 [amdgpu] [99458.372659] Modules linked in: ebtable_filter ebtables netconsole bridge stp llc wireguard curve25519_x86_64 libchacha20poly1305 ip6_udp_tunnel udp_tunnel libblake2s blake2s_x86_64 libcurve25519_generic libblake2s_generic xt_limit xt_comment xt_recent xt_MASQUERADE xt_multiport iptable_nat nf_nat nf_conntrack_netbios_ns nf_conntrack_broadcast xt_CT iptable_raw ip6table_raw snd_seq_midi snd_seq_midi_event uvcvideo videobuf2_vmalloc videobuf2_memops videobuf2_v4l2 videodev amd64_edac_mod snd_usb_audio kvm_amd videobuf2_common kvm snd_usbmidi_lib snd_rawmidi joydev snd_hda_codec_hdmi irqbypass pcspkr snd_hda_intel snd_intel_nhlt snd_hda_codec snd_hwdep sp5100_tco e1000e snd_hda_core snd_pcm tcp_yeah tcp_vegas sch_fq_codel nfsd amdgpu crc32c_intel mgag200 drm_vram_helper gpu_sched ttm vhost_scsi target_core_mod configfs vhost_net tun tap vhost vhba(O) jc42 ipmi_si ipmi_devintf ipmi_msghandler fuse eeprom [99458.452852] CPU: 1 PID: 2240 Comm: X Tainted: G O T 5.4.58-gentoo #1 [99458.460345] Hardware name: Supermicro H8SCM/H8SCM, BIOS 3.5b 03/18/2016 [99458.467620] RIP: 0010:amdgpu_dm_atomic_commit_tail+0x1cce/0x1de0 [amdgpu] [99458.474412] Code: 70 fb ff ff 41 8b 4c 24 60 48 c7 c2 c0 92 59 c0 bf 02 00 00 00 48 c7 c6 28 69 5f c0 e8 0b a0 32 ca 49 8b 57 08 e9 09 e5 ff ff <0f> 0b e9 c3 f0 ff ff 0f 0b 0f 0b e9 d9 f0 ff ff 48 8b 85 38 fd ff [99458.493248] RSP: 0018:ffff9b20c277b840 EFLAGS: 00010002 [99458.498473] RAX: 0000000000000002 RBX: 00000000000004d6 RCX: 0000000000000000 [99458.505634] RDX: 0000000000000001 RSI: 0000000000000206 RDI: 0000000000000000 [99458.512792] RBP: ffff9b20c277bb70 R08: ffff9b20c277b7a4 R09: 0000000000000000 [99458.519941] R10: 0000000000000001 R11: 0000000000000000 R12: 0000000000000286 [99458.527100] R13: ffff8f41ba0b8c00 R14: ffff8f4585fc0000 R15: ffff8f4588b57000 [99458.534254] FS: 00007fc7988b2dc0(0000) GS:ffff8f4696a40000(0000) knlGS:0000000000000000 [99458.542364] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [99458.548129] CR2: 00007f8a3e4eb950 CR3: 0000000811b4c000 CR4: 00000000000406e0 [99458.555287] Call Trace: [99458.557750] ?
