I've installed https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8-rc3/ and the problem seems to have been solved. My laptop is a HP-Pavilion- Laptop-15-cw1xxx, CPU: AMD Ryzen 5 3500U with Radeon Vega Mobile Gfx.

It is not possible to chvt to text terminal when boot is stuck on black screen. Booting with 'nomodeset' kernel option works properly but is not an option (e.g. screen brightness is not adjustable in this case). Another workaround is to ssh to laptop and run systemctl restart display-manager.service. After 5-10 seconds upon executing this command perfectly working login screen appears. Check dmesg. There is apparently related messages from amdgpu driver: ... апр 05 20:46:45 kernel: [drm:amdgpu_dm_set_crtc_irq_state [amdgpu]] *ERROR* amdgpu_dm_set_crtc_irq_state: crtc is NULL at id :3 апр 05 20:46:45 kernel: [drm:amdgpu_dm_set_crtc_irq_state [amdgpu]] *ERROR* amdgpu_dm_set_crtc_irq_state: crtc is NULL at id :3 апр 05 20:46:45 kernel: [drm:amdgpu_dm_set_crtc_irq_state [amdgpu]] *ERROR* amdgpu_dm_set_crtc_irq_state: crtc is NULL at id :3 апр 05 20:46:45 kernel: [drm:amdgpu_dm_set_crtc_irq_state [amdgpu]] *ERROR* amdgpu_dm_set_crtc_irq_state: crtc is NULL at id :3 апр 05 20:46:45 kernel: [drm:amdgpu_dm_set_pflip_irq_state [amdgpu]] *ERROR* amdgpu_dm_set_pflip_irq_state: crtc is NULL at id :3 апр 05 20:46:45 kernel: [drm:amdgpu_dm_set_pflip_irq_state [amdgpu]] *ERROR* amdgpu_dm_set_pflip_irq_state: crtc is NULL at id :3 апр 05 20:46:45 kernel: [drm:amdgpu_dm_set_pflip_irq_state [amdgpu]] *ERROR* amdgpu_dm_set_pflip_irq_state: crtc is NULL at id :3 апр 05 20:46:45 kernel: [drm:amdgpu_dm_set_pflip_irq_state [amdgpu]] *ERROR* amdgpu_dm_set_pflip_irq_state: crtc is NULL at id :3 апр 05 20:46:45 kernel: [drm:amdgpu_dm_set_vupdate_irq_state [amdgpu]] *ERROR* amdgpu_dm_set_vupdate_irq_state: crtc is NULL at id :3 апр 05 20:46:45 kernel: [drm:amdgpu_dm_set_vupdate_irq_state [amdgpu]] *ERROR* amdgpu_dm_set_vupdate_irq_state: crtc is NULL at id :3 апр 05 20:46:45 kernel: [drm:amdgpu_dm_set_vupdate_irq_state [amdgpu]] *ERROR* amdgpu_dm_set_vupdate_irq_state: crtc is NULL at id :3 апр 05 20:46:45 kernel: [drm:amdgpu_dm_set_vupdate_irq_state [amdgpu]] *ERROR* amdgpu_dm_set_vupdate_irq_state: crtc is NULL at id :3 апр 05 20:46:45 kernel: [drm] recover vram bo from shadow start апр 05 20:46:45 kernel: [drm] recover vram bo from shadow done апр 05 20:46:45 kernel: [drm] Skip scheduling IBs! апр 05 20:46:45 kernel: ------------[ cut here ]------------ апр 05 20:46:45 kernel: WARNING: CPU: 3 PID: 793 at include/linux/dma-fence.h:533 drm_sched_resubmit_jobs+0x152/0x160 [gpu_sched] апр 05 20:46:45 kernel: Modules linked in: cmac algif_hash algif_skcipher af_alg bnep zram nls_iso8859_1 snd_hda_codec_realtek snd_hda_codec_generic ledtrig_audio snd_hda_codec_hdmi snd_hda_intel snd_intel_nhlt snd_hda_codec > апр 05 20:46:45 kernel: CPU: 3 PID: 793 Comm: kworker/3:4 Tainted: G OE 5.4.0-21-generic #25-Ubuntu апр 05 20:46:45 kernel: Hardware name: LENOVO 81LY/LNVNB161216, BIOS ARCN32WW 07/11/2019 апр 05 20:46:45 kernel: Workqueue: events drm_sched_job_timedout [gpu_sched] апр 05 20:46:45 kernel: RIP: 0010:drm_sched_resubmit_jobs+0x152/0x160 [gpu_sched] апр 05 20:46:45 kernel: Code: 41 5c 41 5d 41 5e 41 5f 5d c3 49 8b 46 10 31 c9 48 c7 80 80 00 00 00 00 00 00 00 49 8b 7f 70 31 c0 83 e7 01 74 04 0f 0b eb bf <0f> 0b eb c7 0f 0b eb 8b 66 0f 1f 44 00 00 0f 1f 44 00 00 83 7f 4c апр 05 20:46:45 kernel: RSP: 0018:ffffa4dc806d7d28 EFLAGS: 00010246 апр 05 20:46:45 kernel: RAX: 0000000000000000 RBX: 0000000000000001 RCX: 0000000000000000 апр 05 20:46:45 kernel: RDX: ffff8cc9a6fc9180 RSI: ffff8cc9ac4609f8 RDI: 0000000000000000 апр 05 20:46:45 kernel: RBP: ffffa4dc806d7d60 R08: 000000000000047a R09: 0000000000000004 апр 05 20:46:45 kernel: R10: 0000000000000000 R11: 0000000000000001 R12: ffff8cc9ac463c00 апр 05 20:46:45 kernel: R13: ffff8cc9a63c7980 R14: ffff8cc9ac460800 R15: ffff8cc9a6fc9140 апр 05 20:46:45 kernel: FS: 0000000000000000(0000) GS:ffff8cc9b88c0000(0000) knlGS:0000000000000000 апр 05 20:46:45 kernel: CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 апр 05 20:46:45 kernel: CR2: 00007f275ff6c000 CR3: 00000001af148000 CR4: 00000000003406e0 апр 05 20:46:45 kernel: Call Trace: апр 05 20:46:45 kernel: amdgpu_device_gpu_recover+0x6cd/0x95a [amdgpu] апр 05 20:46:45 kernel: amdgpu_job_timedout+0x103/0x130 [amdgpu] апр 05 20:46:45 kernel: drm_sched_job_timedout+0x44/0x90 [gpu_sched] апр 05 20:46:45 kernel: process_one_work+0x1eb/0x3b0 апр 05 20:46:45 kernel: worker_thread+0x4d/0x400 апр 05 20:46:45 kernel: kthread+0x104/0x140 апр 05 20:46:45 kernel: ? process_one_work+0x3b0/0x3b0 апр 05 20:46:45 kernel: ? kthread_park+0x90/0x90 апр 05 20:46:45 kernel: ret_from_fork+0x22/0x40 апр 05 20:46:45 kernel: ---[ end trace fb203c8f6a7afd49 ]--- ...
