Hi Micky, I am trying to debug a lenovo T450s laptop with a Realtek rts5227 sd reader on it. I was wondering if you can help me figure things out. I am seeing the following when I insert a regular (not micro) SDXC Transcend 64GB card and try and mount it: mmc0: cannot verify signal voltage switch mmc0: new ultra high speed SDR104 SDXC card at address 59b4 mmcblk0: mmc0:59b4 SDU1 59.8 GiB mmcblk0: p1 EXT4-fs (mmcblk0p1): mounted filesystem with ordered data mode. Opts: (null) mmcblk0: unknown error -22 sending read/write command, card status 0x900 mmc0: cannot verify signal voltage switch I was focusing on the -22 error. It seems to be an -EINVAL set because a read transaction failed with TRANS_FAIL_INT. Everything else seems fine. The mount succeeds and I can r/w data. This is with the latest 4.8 kernel (older kernels have the same error too). Turning on debugging it seems to be a CRC error? but the driver can recover and move on. So the warning seems harmless. Nonetheless various Fedora and RHEL folks are bothered by it and I wanted to figure out how to fix it correctly. I have attached some debug logs below with MMC_DEBUG enabled and a bunch of dynamic_debug turned on to help. Thoughts? Cheers, Don [ 333.249114] mmc0: starting CMD18 arg 078bf7f0 flags 000000b5 [ 333.249115] mmc0: blksz 512 blocks 8 flags 00000200 tsac 100 ms nsac 0 [ 333.249116] mmc0: CMD12 arg 00000000 flags
