RE: MMC timeout issue on 4.6 kernel

[Sai Krishna Potthuri]

Hi All,

With further debug, I am seeing the issue only with ADMA2, whereas SDMA and PIO mode are working fine.
Can anyone help me on this issue?

Regards
Sai Krishna

You should use git bisect to find the failing commit.

What driver is it?

Does the problem still happen on 4.8? Or stable kernels?

Hi,

>

It is failing after many successful runs, issue occurring in regression sometimes after 4 to 5hrs.
So, it is taking lot of time to test a single commit. Anyway I will do this if I don't have any
Other option.

Tried on 4.7 kernel, didn't see the issue.

MMC timeout issue on 4.6 kernel

[Sai Krishna Potthuri]

Hi,

With 4.6 kernel, I am doing regression test on SD which does following things.
1. Mount SD card.
2. Read and write random 1MB data.
3. Reboot the board.

I am facing following error while reading the data from the SD card. 

mmc0: Timeout waiting for hardware interrupt.
mmcblk0: error -110 transferring data, sector 8194, nr 2, cmd response 0x900, card status 0xb00
mmc0: tried to reset card
mmc0: Timeout waiting for hardware interrupt.
mmcblk0: error -110 transferring data, sector 8194, nr 2, cmd response 0x900, card status 0xb00
mmcblk0: retrying using single block read
mmc0: Timeout waiting for hardware interrupt.
mmcblk0: error -110 transferring data, sector 8194, nr 2, cmd response 0x900, card status 0x0
blk_update_request: I/O error, dev mmcblk0, sector 8194
mmc0: Timeout waiting for hardware interrupt.
mmcblk0: error -110 transferring data, sector 8195, nr 1, cmd response 0x900, card status 0x0
blk_update_request: I/O error, dev mmcblk0, sector 8195
EXT2-fs (mmcblk0p1): error: unable to read superblock
mmc0: Timeout waiting for hardware interrupt.
mmcblk0: error -110 transferring data, sector 16387, nr 61, cmd response 0x900, card status 0xb00
mmc0: tried to reset card

Getting this error once in a while in regression test after several runs.
I am not seeing this issue with 4.5 kernel.
Please let me know if anyone has seen this issue.

Regards
Sai Krishna
