  "message": "gfx gma skylake: Implement some workarounds\n\nWithout these workarounds, gfx_test will leave a WHL-U Librem Mini v1 in\na state where entering low-power states results in a hang. With these\nworkarounds, the system no longer locks up after running gfx_test. Looks\nlike the hang does not happen when coreboot runs libgfxinit.\n\nSteps to reproduce the hang:\n- Boot Linux without loading i915.\n- Run gfx_test without the workarounds.\n- After gfx_test exits and the machine enters a low-power state,\n  it will lock up.\n\nIf something keeps the CPU from getting into low-power states (e.g.\n`cat /dev/zero \u003e /dev/null`), the machine will not lock up. However,\nstopping the load task after gfx_test has run will result in a lock-up.\n\nChange-Id: I4cd64cf4c1e702dc05709adc345a976a4e3c1ded\nSigned-off-by: Angel Pons \u003cth3fanbus@gmail.com\u003e\nReviewed-on: https://review.coreboot.org/c/libgfxinit/+/46635\nReviewed-by: Nico Huber \u003cnico.h@gmx.de\u003e\n",
