Hi, with 5.3.0-53 generic, i've encountered 2 errors that have frozen the system during 2 or 3 minutes. After this error, the system came back to normal. These 2 errors has been observed with Kodi at the "beginning" of the session (in the firts minutes after a boot), and only once per boot. I'm still testing. Here is the syslog when an error occurs:

No particular triggers identified although have Chrome / Chromium running with Hardware Acceleration enabled does appear to increase the frequency. I have seen incidences of these hangs in jounralctl output using previous kernels in the 5.3.0-xx series but they were very infrequent (one or twice in a week of daily usage) System Info steve@steve-Inspiron-5580:~$ inxi -SCGxxxz System: Host: steve-Inspiron-5580 Kernel: 5.3.0-46-generic x86_64 bits: 64 compiler: gcc v: 7.5.0 Desktop: Cinnamon 4.4.8 wm: muffin 4.4.2 dm: LightDM 1.26.0 Distro: Linux Mint 19.3 Tricia base: Ubuntu 18.04 bionic CPU: Topology: Quad Core model: Intel Core i5-8265U bits: 64 type: MT MCP arch: Kaby Lake rev: B L2 cache: 6144 KiB flags: avx avx2 lm nx pae sse sse2 sse3 sse4_1 sse4_2 ssse3 vmx bogomips: 28800 Speed: 1173 MHz min/max: 400/3900 MHz Core speeds (MHz): 1: 800 2: 800 3: 800 4: 800 5: 800 6: 800 7: 800 8: 800 Graphics: Device-1: Intel vendor: Dell driver: i915 v: kernel bus ID: 00:02.0 chip ID: 8086:3ea0 Display: x11 server: X.Org 1.20.5 driver: modesetting unloaded: fbdev,vesa resolution: 1920x1080~60Hz OpenGL: renderer: Mesa DRI Intel UHD Graphics (Whiskey Lake 3x8 GT2) v: 4.5 Mesa 19.2.8 compat-v: 3.0 direct render: Yes steve@steve-Inspiron-5580:~$ journalctl -b | grep i915 Apr 10 06:15:17 steve-Inspiron-5580 kernel: i915 0000:00:02.0: vgaarb: deactivate vga console Apr 10 06:15:17 steve-Inspiron-5580 kernel: i915 0000:00:02.0: vgaarb: changed VGA decodes: olddecodes=io+mem,decodes=io+mem:owns=io+mem Apr 10 06:15:17 steve-Inspiron-5580 kernel: [drm] Finished loading DMC firmware i915/kbl_dmc_ver1_04.bin (v1.4) Apr 10 06:15:17 steve-Inspiron-5580 kernel: [drm] Initialized i915 1.6.0 20190619 for 0000:00:02.0 on minor 0 Apr 10 06:15:17 steve-Inspiron-5580 kernel: fbcon: i915drmfb (fb0) is primary device Apr 10 06:15:17 steve-Inspiron-5580 kernel: i915 0000:00:02.0: fb0: i915drmfb frame buffer device Apr 10 06:15:17 steve-Inspiron-5580 kernel: snd_hda_intel 0000:00:1f.3: bound 0000:00:02.0 (ops i915_audio_component_bind_ops [i915]) Apr 10 06:16:28 steve-Inspiron-5580 kernel: i915 0000:00:02.0: GPU HANG: ecode 9:0:0x00000000, hang on rcs0 Apr 10 06:16:28 steve-Inspiron-5580 kernel: i915 0000:00:02.0: Resetting rcs0 for hang on rcs0 Apr 10 06:31:46 steve-Inspiron-5580 kernel: i915 0000:00:02.0: Resetting rcs0 for hang on rcs0 Apr 10 06:37:48 steve-Inspiron-5580 kernel: i915 0000:00:02.0: Resetting rcs0 for hang on rcs0 Apr 10 06:40:46 steve-Inspiron-5580 kernel: i915 0000:00:02.0: Resetting rcs0 for hang on rcs0 I note another user has reported similar issues on the same kernel at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1861395/comments/52 --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.14 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: steve 3920 F.... pulseaudio /dev/snd/pcmC0D0p: steve 3920 F...m pulseaudio CurrentDesktop: X-Cinnamon DistroRelease: Linux Mint 19.3 HibernationDevice: RESUME=none InstallationDate: Installed on 2019-12-27 (104 days ago) InstallationMedia: Linux Mint 19.3 "Tricia" - Release amd64 20191213 MachineType: Dell Inc.
