Working with rootfs on two 128GB mmcs on rk3399-roc-pc. 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.
