Receiving errors about eMMC (?)

[gusarg81]

Hi!

    I am having the same exact problems, and both my Rock64 and the eMMc memory (32GB) are brand new!

To many lines of them... Now if i have to analice this, is a typical debug of a bad drive, which in this case, is the eMMC. But seems I am not alone and maybe is something with the Rock64 hardware?

By the way, I am using Debian Stretch (from a OpenMediaVault image).

Any ideas? Thanks.
