One (mmc name 128G72, one screw hole) works fine in HS400 mode. Other (mmc name DJNB4R, firefly on pcb, two screw holes) gets lots of mmc1: "running CQE recovery", even hangs with damaged fs, when running under heavy load, e.g. compiling kernel. Both run fine with HS200. Disabling CQ with patch mmc: core: Add MMC Command Queue Support kernel parameter [0] did not help. [0] https://gitlab.com/ayufan-repos/rock64/linux-mainline-kernel/commit/54e264154b87dfe32a8359b2726e2d5611adbaf3 Therefore I propose to disable HS400 mode on roc-pc for now.
