** Description changed: With new Kubuntu 21.10 installation I experienced instabilities of my work system (when letting the system run over night, at morning the system rebooted by itself and asks for disk encryption password). I had a look into the kernel log and I found an incident that may be is related to the instability. Anyway there seems to be something going - wrong: + wrong. - Dec 23 04:10:28 mypc kernel: [15910.599072] WARNING: CPU: 6 PID: 2834 at drivers/gpu/drm/ttm/ttm_bo.c:437 ttm_bo_release+0x2de/0x330 [ttm] - Dec 23 04:10:28 mypc kernel: [15910.599082] Modules linked in: md4 nls_utf8 cifs libarc4 fscache netfs libdes vmnet(OE) vmw_vsock_vmci_transport vsock vmw_vmci vmmon(OE) rfcomm nvidia_uvm(PO) cmac algif_hash algif_skcipher af_alg bnep nvidia_drm(PO) intel_rapl_msr intel_rapl_common amd64_edac edac_mce_amd nvidia_modeset(PO) nls_iso8859_1 nvidia(PO) snd_hda_codec_realtek snd_hda_codec_generic ledtrig_audio snd_hda_codec_hdmi snd_hda_intel snd_intel_dspcfg snd_intel_sdw_acpi snd_hda_codec snd_usb_audio uvcvideo snd_hda_core videobuf2_vmalloc snd_usbmidi_lib videobuf2_memops snd_hwdep btusb snd_seq_midi snd_seq_midi_event btrtl snd_pcm btbcm input_leds joydev snd_rawmidi btintel videobuf2_v4l2 snd_seq kvm bluetooth videobuf2_common snd_seq_device snd_timer videodev snd ecdh_generic mc eeepc_wmi wmi_bmof efi_pstore mxm_wmi rapl ecc ccp k10temp soundcore mac_hid sch_fq_codel msr parport_pc ppdev binfmt_misc lp parport ip_tables x_tables autofs4 btrfs blake2b_generic xor zstd_compress raid6_pq libcrc32c dm_crypt hid_generic - Dec 23 04:10:28 mypc kernel: [15910.599125] usbhid hid radeon i2c_algo_bit mfd_aaeon drm_ttm_helper ttm asus_wmi sparse_keymap drm_kms_helper video syscopyarea sysfillrect sysimgblt crct10dif_pclmul fb_sys_fops crc32_pclmul cec ghash_clmulni_intel rc_core aesni_intel crypto_simd drm cryptd igc nvme ahci xhci_pci gpio_amdpt i2c_piix4 xhci_pci_renesas libahci nvme_core wmi gpio_generic - Dec 23 04:10:28 mypc kernel: [15910.599146] CPU: 6 PID: 2834 Comm: kwin_x11:rcs0 Tainted: P OE 5.13.0-22-generic #22-Ubuntu - Dec 23 04:10:28 mypc kernel: [15910.599148] Hardware name: ASUS System Product Name/ROG STRIX B550-E GAMING, BIOS 2201 04/07/2021 - Dec 23 04:10:28 mypc kernel: [15910.599149] RIP: 0010:ttm_bo_release+0x2de/0x330 [ttm] - Dec 23 04:10:28 mypc kernel: [15910.599154] Code: e8 87 0a 17 fc e9 ac fd ff ff 49 8b 7e 98 b9 4c 1d 00 00 31 d2 be 01 00 00 00 e8 bd 2d 17 fc 49 8b 46 e8 eb 9d 4c 89 e0 eb 98 <0f> 0b 41 c7 86 84 00 00 00 00 00 00 00 49 8d 76 08 31 d2 4c 89 ef - Dec 23 04:10:28 mypc kernel: [15910.599156] RSP: 0018:ffffb9060456fca8 EFLAGS: 00010206 - Dec 23 04:10:28 mypc kernel: [15910.599157] RAX: 0000000000000003 RBX: 0000000000000001 RCX: 0000000000000000 - Dec 23 04:10:28 mypc kernel: [15910.599158] RDX: 0000000000000001 RSI: ffff8abf80059c00 RDI: ffff8abf9a6b0ef8 - Dec 23 04:10:28 mypc kernel: [15910.599159] RBP: ffffb9060456fcd0 R08: 0000000000000000 R09: 0000000000000001 - Dec 23 04:10:28 mypc kernel: [15910.599160] R10: ffff8ac060210938 R11: ffff8abf8a2b4310 R12: ffff8abf9a6b06e8 - Dec 23 04:10:28 mypc kernel: [15910.599161] R13: ffff8abf8a196c78 R14: ffff8abf8a196dd8 R15: ffff8abf941b2940 - Dec 23 04:10:28 mypc kernel: [15910.599162] FS: 00007f5dc23bf640(0000) GS:ffff8ac68eb80000(0000) knlGS:0000000000000000 - Dec 23 04:10:28 mypc kernel: [15910.599164] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 - Dec 23 04:10:28 mypc kernel: [15910.599165] CR2: 00007f2972d3b000 CR3: 000000010e720000 CR4: 0000000000750ee0 - Dec 23 04:10:28 mypc kernel: [15910.599166] PKRU: 55555554 - Dec 23 04:10:28 mypc kernel: [15910.599167] Call Trace: - Dec 23 04:10:28 mypc kernel: [15910.599170] ttm_bo_put+0x30/0x50 [ttm] - Dec 23 04:10:28 mypc kernel: [15910.599174] radeon_bo_unref+0x1e/0x30 [radeon] - Dec 23 04:10:28 mypc kernel: [15910.599199] radeon_gem_object_free+0x34/0x50 [radeon] - Dec 23 04:10:28 mypc kernel: [15910.599222] drm_gem_object_free+0x1d/0x30 [drm] - Dec 23 04:10:28 mypc kernel: [15910.599241] drm_gem_dmabuf_release+0x40/0x60 [drm] - Dec 23 04:10:28 mypc kernel: [15910.599261] dma_buf_release+0x46/0x90 - Dec 23 04:10:28 mypc kernel: [15910.599265] __dentry_kill+0x10e/0x190 - Dec 23 04:10:28 mypc kernel: [15910.599269] dentry_kill+0x52/0x1c0 - Dec 23 04:10:28 mypc kernel: [15910.599271] dput+0x12f/0x180 - Dec 23 04:10:28 mypc kernel: [15910.599272] __fput+0xf0/0x250 - Dec 23 04:10:28 mypc kernel: [15910.599274] ____fput+0xe/0x10 - Dec 23 04:10:28 mypc kernel: [15910.599275] task_work_run+0x6d/0xa0 - Dec 23 04:10:28 mypc kernel: [15910.599278] exit_to_user_mode_loop+0x150/0x160 - Dec 23 04:10:28 mypc kernel: [15910.599281] exit_to_user_mode_prepare+0x9f/0xb0 - Dec 23 04:10:28 mypc kernel: [15910.599283] syscall_exit_to_user_mode+0x27/0x50 - Dec 23 04:10:28 mypc kernel: [15910.599286] do_syscall_64+0x6e/0xb0 - Dec 23 04:10:28 mypc kernel: [15910.599288] ?
