Receiving errors about eMMC (?)

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.

Mine is a Forsesee 16 gb.  Again, I'll report back if the contact cleaner fix holds up. I would be interested in some actual memory benchmark test comparisons.  But in general I have a lot of confidence in Samsung chips.

I looked at the odroid site. Are all of those versions to do with the pre-installed OS? I would think that an emmc chip should be standard and work in any device like an SD card. Am I missing something?
