Sorry, I didn’t answer for a long time. The results of my tests surprised me a bit: - kernel 5.5.2 works fine, even though I had to recompile the VirtualBox kernel module with GCC 9 - kernel 5.3.18 works fine - kernel 4.20.17 works fine - kernel 4.15.0.87 (last updates) run into the same problem as before: Feb 10 03:30:19 localhost kernel: [32746.808522] ------------[ cut here ]------------ Feb 10 03:30:19 localhost kernel: [32746.808525] WARN_ON(fbc->active) Feb 10 03:30:19 localhost kernel: [32746.808735] WARNING: CPU: 3 PID: 14663 at /build/linux-hwe-LVnYcm/linux-hwe-4.15.0/drivers/gpu/drm/i915/intel_fbc.c:1136 intel_fbc_enable+0x3ed/0x570 [i915] Feb 10 03:30:19 localhost kernel: [32746.808738] Modules linked in: vboxnetadp(OE) vboxnetflt(OE) vboxdrv(OE) ccm rfcomm bnep zfs(PO) zunicode(PO) zavl(PO) icp(PO) zcommon(PO) znvpair(PO) spl(O) rtsx_usb_ms memstick uvcvideo videobuf2_vmalloc videobuf2_memops videobuf2_v4l2 videobuf2_core videodev media arc4 iwlmvm mac80211 snd_hda_codec_hdmi snd_soc_skl snd_soc_skl_ipc snd_hda_ext_core snd_soc_sst_dsp snd_hda_codec_realtek snd_soc_sst_ipc snd_soc_acpi snd_hda_codec_generic snd_soc_core intel_rapl x86_pkg_temp_thermal intel_powerclamp coretemp snd_compress ac97_bus kvm_intel snd_pcm_dmaengine snd_hda_intel kvm snd_hda_codec irqbypass snd_hda_core crct10dif_pclmul crc32_pclmul snd_hwdep ghash_clmulni_intel pcbc snd_pcm snd_seq_midi snd_seq_midi_event aesni_intel aes_x86_64 crypto_simd glue_helper cryptd snd_rawmidi intel_cstate intel_rapl_perf Feb 10 03:30:19 localhost kernel: [32746.808808] snd_seq joydev snd_seq_device snd_timer input_leds wmi_bmof intel_wmi_thunderbolt serio_raw snd btusb btrtl btbcm btintel soundcore iwlwifi bluetooth ecdh_generic cfg80211 shpchp mei_me mei intel_pch_thermal ideapad_laptop sparse_keymap acpi_pad mac_hid parport_pc ppdev lp parport autofs4 btrfs xor zstd_compress raid6_pq hid_generic i915 i2c_algo_bit rtsx_usb_sdmmc drm_kms_helper usbhid syscopyarea sysfillrect sysimgblt rtsx_usb hid fb_sys_fops psmouse r8169 ahci drm mii libahci wmi video Feb 10 03:30:19 localhost kernel: [32746.808870] CPU: 3 PID: 14663 Comm: kworker/u8:0 Tainted: P OE 4.15.0-87-generic #87~16.04.1-Ubuntu Feb 10 03:30:19 localhost kernel: [32746.808873] Hardware name: LENOVO 80SY/, BIOS 0ZCN30WW 12/08/2016 Feb 10 03:30:19 localhost kernel: [32746.808996] Workqueue: events_unbound intel_atomic_commit_work [i915] Feb 10 03:30:19 localhost kernel: [32746.809112] RIP: 0010:intel_fbc_enable+0x3ed/0x570 [i915] Feb 10 03:30:19 localhost kernel: [32746.809116] RSP: 0018:ffffb11005aa7cb0 EFLAGS: 00010286 Feb 10 03:30:19 localhost kernel: [32746.809121] RAX: 0000000000000000 RBX: ffff8e19a9fe0000 RCX: 0000000000000000 Feb 10 03:30:19 localhost kernel: [32746.809124] RDX: 0000000000000014 RSI: ffffffff9675bc34 RDI: 0000000000000246 Feb 10 03:30:19 localhost kernel: [32746.809127] RBP: ffffb11005aa7d00 R08: fffffffa8539e412 R09: ffffffffffffffff Feb 10 03:30:19 localhost kernel: [32746.809130] R10: ffffb11005aa7c88 R11: 000000000000037a R12: ffff8e17f22e5000 Feb 10 03:30:19 localhost kernel: [32746.809133] R13: ffff8e19b0efdb00 R14: ffff8e193ab5a800 R15: ffff8e19a9fe0000 Feb 10 03:30:19 localhost kernel: [32746.809138] FS: 0000000000000000(0000) GS:ffff8e19bed80000(0000) knlGS:0000000000000000 Feb 10 03:30:19 localhost kernel: [32746.809142] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 Feb 10 03:30:19 localhost kernel: [32746.809145] CR2: 00000000e120e000 CR3: 0000000143a0a005 CR4: 00000000003626e0 Feb 10 03:30:19 localhost kernel: [32746.809148] Call Trace: Feb 10 03:30:19 localhost kernel: [32746.809262] ? intel_pre_plane_update+0x12f/0x190 [i915] Feb 10 03:30:19 localhost kernel: [32746.809371] intel_update_crtc+0x75/0xa0 [i915] Feb 10 03:30:19 localhost kernel: [32746.809477] skl_update_crtcs+0x1a9/0x1f0 [i915] Feb 10 03:30:19 localhost kernel: [32746.809596] intel_atomic_commit_tail+0x3c8/0xe00 [i915] Feb 10 03:30:19 localhost kernel: [32746.809607] ? __switch_to+0x9b/0x4e0 Feb 10 03:30:19 localhost kernel: [32746.809616] ? __switch_to_asm+0x35/0x70 Feb 10 03:30:19 localhost kernel: [32746.809720] intel_atomic_commit_work+0x12/0x20 [i915] Feb 10 03:30:19 localhost kernel: [32746.809729] process_one_work+0x14d/0x410 Feb 10 03:30:19 localhost kernel: [32746.809736] worker_thread+0x4b/0x460 Feb 10 03:30:19 localhost kernel: [32746.809742] kthread+0x105/0x140 Feb 10 03:30:19 localhost kernel: [32746.809749] ? process_one_work+0x410/0x410 Feb 10 03:30:19 localhost kernel: [32746.809754] ? kthread_bind+0x40/0x40 Feb 10 03:30:19 localhost kernel: [32746.809762] ret_from_fork+0x35/0x40 Feb 10 03:30:19 localhost kernel: [32746.809767] Code: 4a 03 00 00 00 0f 84 55 01 00 00 80 bb ca 2c 00 00 00 0f 84 1c ff ff ff 48 c7 c6 5e 44 6e c0 48 c7 c7 44 44 6e c0 e8 a3 00 83 d4 <0f> 0b e9 02 ff ff ff 3d 00 08 00 00 ba 00 08 00 00 0f 4f c2 e9 Feb 10 03:30:19 localhost kernel: [32746.809838] ---[ end trace 82e85d01278b82eb ]---
Do not know, is it really dangerous or not. My notebook still works. All tests were carried out during the all night with the sound through HDMI and with VirtualBox running MS Windows as guest OS, which was doing something all the time. Everything was the same way as before, when I had problems. Probably i'll stay on 5.5 kernel. Thank you all for the help. See you when new bugs will appear. вт, 4 февр. 2020 г. в 17:33, Valery Frolov <fvg...@gmail.com>: > will try in 3-4 days. thanks a lot! > > respectfully > valerii frolov > > > С уважением. > Валерий Фролов > ООО "АСУ-Проект", г.
