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
