Seems to happen more often if the graphic card load is increased. Might be related to the graphic card core temperature/load-related. Fixed the problem by adding the following kernel option : i915.enable_psr=0 [ 3.868968] i915 0000:00:02.0: [drm] Unknown revid 0x06 [ 3.869555] i915 0000:00:02.0: [drm] VT-d active for gfx access [ 3.869566] fb0: switching to i915 from EFI VGA [ 3.869878] i915 0000:00:02.0: vgaarb: deactivate vga console [ 3.921387] i915 0000:00:02.0: [drm] couldn't get memory information [ 3.922325] i915 0000:00:02.0: vgaarb: changed VGA decodes: olddecodes=io+mem,decodes=io+mem:owns=io+mem [ 3.923660] i915 0000:00:02.0: [drm] Finished loading DMC firmware i915/glk_dmc_ver1_04.bin (v1.4) [ 4.222037] [drm] Initialized i915 1.6.0 20201103 for 0000:00:02.0 on minor 0 [ 4.222440] snd_hda_intel 0000:00:0e.0: bound 0000:00:02.0 (ops i915_audio_component_bind_ops [i915]) [ 4.561945] fbcon: i915drmfb (fb0) is primary device [ 4.593816] i915 0000:00:02.0: [drm] fb0: i915drmfb frame buffer device [ 4954.090871] i915 0000:00:02.0: [drm] *ERROR* CPU pipe A FIFO underrun Machine has latest firmware (CoreBoot) And its Ubuntu is the latest LTS, kept up to date.
