I can also confirm that this problem continues in 5.3.0-51-generic However, I see it very frequently (not just for 5 seconds... happening all the time) with two different use cases.
1) When i have a headset (with a mic) plugged into the front audio port. One of my cores also goes to 100% utilization. or 2) When I run Zoom conferencing software. Here is the journalctl output with 5.3.0-51-generic: journalctl -b | grep i915 Apr 30 08:02:17 breath-mint kernel: i915 0000:00:02.0: vgaarb: deactivate vga console Apr 30 08:02:17 breath-mint kernel: i915 0000:00:02.0: vgaarb: changed VGA decodes: olddecodes=io+mem,decodes=io+mem:owns=io+mem Apr 30 08:02:17 breath-mint kernel: [drm] Finished loading DMC firmware i915/kbl_dmc_ver1_04.bin (v1.4) Apr 30 08:02:17 breath-mint kernel: [drm] Initialized i915 1.6.0 20190619 for 0000:00:02.0 on minor 1 Apr 30 08:02:17 breath-mint kernel: fbcon: i915drmfb (fb0) is primary device Apr 30 08:02:17 breath-mint kernel: i915 0000:00:02.0: fb0: i915drmfb frame buffer device Apr 30 08:02:26 breath-mint kernel: snd_hda_intel 0000:00:1f.3: bound 0000:00:02.0 (ops i915_audio_component_bind_ops [i915]) Apr 30 08:03:11 breath-mint kernel: [drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe B (start=4635 end=4636) time 115 us, min 1073, max 1079, scanline start 1072, end 1080 Apr 30 08:04:15 breath-mint kernel: [drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe B (start=8521 end=8522) time 130 us, min 1073, max 1079, scanline start 1072, end 1081 Apr 30 08:04:40 breath-mint kernel: i915 0000:00:02.0: GPU HANG: ecode 9:0:0x00000000, hang on rcs0 Apr 30 08:04:40 breath-mint kernel: i915 0000:00:02.0: Resetting rcs0 for hang on rcs0 Apr 30 08:04:48 breath-mint kernel: i915 0000:00:02.0: Resetting rcs0 for hang on rcs0 Apr 30 08:04:56 breath-mint kernel: i915 0000:00:02.0: Resetting rcs0 for hang on rcs0 My temporary work around is to downgrade my kernel to 5.0. I do not experience the problem there.
