I've been fighting this for a week.
Conclusions:
1) Ayufan's kernel has emmc freq set too high to be stable on some (most?) emmc modules https://github.com/ayufan-rock64/linux-k...4.dts#L234 should be 150000000 ,same as in rockchip-linux repo.
2) Foresee emmc modules sold in the shop are CRAP. I'm currently using hardkernel (odroid-c2) emmc which are made from samsung flash chips, runs like a charm and is at least two times faster than Foresee (subjective, I don't have any benchmark results handy to back this claim)
Note: I'm no longer using ayufan's kernels, I build my own from rockchip-linux bsp repo plus tweaked dtsi/dts.
