Commit: bfa738cf3dfa (Today's Linus tree HEAD)
defconfig: arch/arm64/configs/defconfig
DT: arch/arm64/boot/dts/socionext/uniphier-ld20-ref.dts


I am using eMMC (/dev/mmcblk0) as a disk.

The eMMC driver is in upstream (drivers/mmc/host/sdhci-cadence.c)



"test_resume" seems to work.


The full log is as follows:
