FS#1242 - SATA broken on kernel 4.9 on mt7621

No idea. I've tried it on the 4.4 kernel and it seems to work well. I'm using it for the sd card though (the mmc driver breaks when using the HighMem zone). Could also help here since the issue for me happens after 15+ hours.

I don't think those two options have any impact.
