kernel: i915 0000:00:02.0: [drm] *ERROR* CPU pipe A FIFO underrun

Screen flickering

Panel Self Refresh (PSR), a power saving feature used by Intel iGPUs is known to cause flickering in some instances FS#49628 FS#49371 FS#50605. A temporary solution is to disable this feature using the kernel parameter i915.enable_psr=0 or xe.enable_psr=0.

Recommended Solutions
  • Disable Panel Self Refresh (PSR): Add i915.enable_psr=0 to your GRUB boot parameters (usually in /etc/default/grub under GRUB_CMDLINE_LINUX_DEFAULT).
  • Disable IOMMU: Add intel_iommu=igfx_off to the GRUB command line.
  • Update/Change Kernel: If the issue started after a kernel update (e.g., to 6.9 or newer), consider using an LTS kernel, as this is a recurring compatibility issue.
  • Disable Intel FBC: Add i915.enable_fbc=0 to boot parameters.
  • Modify C-States: If the system freezes, try adding intel_idle.max_cstate=2 to the kernel boot parameters.
