Thank you so much. I was not yet able to investigate the crash (it usually happens during a video call and then I quickly need to reboot, to continue chatting with the customer - no time to diagnose :-D )
However, today I found out something in the log that might be connected (even though in this case nothing crashed, the computer seems to be continuing just fine): [ 2090.256068] ------------[ cut here ]------------ [ 2090.256153] WARNING: CPU: 5 PID: 6749 at drivers/gpu/drm/nouveau/nvif/vmm.c:68 nvif_vmm_put+0x6d/0x80 [nouveau] [ 2090.256154] Modules linked in: ccm rfcomm aufs cmac algif_hash overlay algif_skcipher af_alg bnep binfmt_misc dm_multipath scsi_dh_rdac scsi_dh_emc scsi_dh_alua snd_hda_codec_hdmi intel_rapl_msr mei_hdcp intel_rapl_common iwlmvm x86_pkg_temp_thermal intel_powerclamp coretemp mac80211 kvm_intel snd_hda_codec_realtek libarc4 snd_hda_codec_generic kvm rmi_smbus snd_usb_audio rmi_core uvcvideo snd_usbmidi_lib intel_cstate intel_rapl_perf videobuf2_vmalloc snd_hda_intel serio_raw btusb iwlwifi videobuf2_memops snd_intel_dspcfg videobuf2_v4l2 btrtl snd_seq_midi snd_hda_codec videobuf2_common snd_seq_midi_event snd_rawmidi btbcm snd_hda_core btintel intel_wmi_thunderbolt videodev input_leds joydev snd_hwdep wmi_bmof snd_seq thinkpad_acpi bluetooth rtsx_pci_ms mc snd_pcm memstick cfg80211 nvram ledtrig_audio mei_me ecdh_generic snd_seq_device ecc intel_pch_thermal mei snd_timer snd soundcore mac_hid sch_fq_codel cuse parport_pc ppdev lp parport ip_tables x_tables autofs4 btrfs zstd_compress [ 2090.256181] hid_generic usbhid hid dm_crypt raid10 raid456 async_raid6_recov async_memcpy async_pq async_xor async_tx xor raid6_pq libcrc32c raid1 raid0 multipath linear crct10dif_pclmul crc32_pclmul ghash_clmulni_intel rtsx_pci_sdmmc nouveau aesni_intel crypto_simd mxm_wmi i2c_algo_bit ttm drm_kms_helper syscopyarea sysfillrect cryptd sysimgblt glue_helper fb_sys_fops psmouse drm e1000e i2c_i801 rtsx_pci ahci libahci wmi video [ 2090.256215] CPU: 5 PID: 6749 Comm: chrome Not tainted 5.4.0-31-generic #35-Ubuntu [ 2090.256215] Hardware name: LENOVO 20EN0005MS/20EN0005MS, BIOS N1EET87W (1.60 ) 12/06/2019 [ 2090.256263] RIP: 0010:nvif_vmm_put+0x6d/0x80 [nouveau] [ 2090.256283] Code: 00 00 48 8d 55 e0 be 02 00 00 00 48 c7 45 e0 00 00 00 00 48 89 45 e8 e8 71 e5 ff ff 85 c0 75 0a 48 c7 43 08 00 00 00 00 eb b7 <0f> 0b eb f2 e8 ea 26 7f ed 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 44 [ 2090.256284] RSP: 0018:ffffa8d503f27bc8 EFLAGS: 00010282 [ 2090.256286] RAX: 00000000fffffffe RBX: ffffa8d503f27bf8 RCX: 0000000000000000 [ 2090.256287] RDX: 0000000000000010 RSI: ffffa8d503f27b38 RDI: ffffa8d503f27bd8 [ 2090.256287] RBP: ffffa8d503f27be8 R08: 0000000000000000 R09: 0000000000000000 [ 2090.256288] R10: 0000000000000030 R11: ffff927e7fc8f640 R12: ffffa8d503f27c30 [ 2090.256289] R13: ffff927f64fee0b0 R14: 0000000000000000 R15: ffff927e7fc8f638 [ 2090.256290] FS: 00007f0fb553bb00(0000) GS:ffff927f6c340000(0000) knlGS:0000000000000000 [ 2090.256291] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 2090.256291] CR2: 000055bdb8317000 CR3: 000000088824a003 CR4: 00000000003606e0 [ 2090.256292] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 2090.256306] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [ 2090.256306] Call Trace: [ 2090.256362] nouveau_vma_del+0x75/0xc0 [nouveau] [ 2090.256402] nouveau_gem_object_close+0x1f5/0x210 [nouveau] [ 2090.256416] drm_gem_object_release_handle+0x35/0xa0 [drm] [ 2090.256427] drm_gem_handle_delete+0x59/0xa0 [drm] [ 2090.256449] ?

Curiously the music continues to play (and e.g. sound from youtube video continues to be played even though the video itself freezes and no longer animates on-screen). It appears that the freeze happens quite randomly; I am not able to figure out what it's caused by. Sometimes it's caused by launching the Snap Chromium, or perhaps by a notification shown, but I do not know for sure. I also tried to hunt system logs and/or systemd gnome-shell logs, but I failed to discover some kind of crash dump. Curiously the Ctrl+Alt+F2 key combo stops working. That leads me to believe that it's some kind of kernel+nouveau crash, but I can't seem to discover any kernel panic in the system logs. After the gnome-shell freezes, the numlock light still responds to numlock key presses. However, mashing Ctrl+Alt+Del has no effect, so I'm only able to reboot via Alt+Sysrq+s u b.
