Hi Wolfram,

I'm seeing SD card errors on Hikey board with 4.13-rc kernel. Full log can be found at the bottom.

As it's never seen before with 4.12, I ran bisect down to the following commits.

9820a5b11101 (mmc: core: for data errors, take response of stop cmd into account) a04e6bae9e6f (mmc: core: check also R1 response for stop commands)

I understand that the commits might just expose the problem with my platform (dw_mmc-k3 driver, Kingston 16GB UHS-I card). But I'd like to fix the problem, so I appreciate it if you can give some suggestion on where I should start looking into. Thanks.

Shawn

I also tested this patch and it could resolve the issue. So, I would like to send my "Tested-by" for the patch. But, I realized my linux-mmc subscription was ended now...

To Ulf-san,

If possible, could you add my "Tested-by" on the patch below?
https://patchwork.kernel.org/patch/9884197/

Tested-by Yoshihiro Shimoda <[email protected]>

< Testing method >
- Connect 1GB sd card to my environment (H3 on Salvator-X)
- I ran the following command:

  # dd if=/dev/mmcblk1 of=/dev/null bs=512k skip=1700

Best regards,
Yoshihiro Shimoda
