imx28 mmcblk0: retrying using single block read

shashikanthirem — Sun, 07 Jun 2020 03:20:19 GMT

Hi all,

i am using kernel 2.6.35.10,

i am calling statvfs("/mnt/mmcblk0p1", &info); with a gap of 500ms in a while(1); -- > this is to get the status of various size like used , free, and available space

but when i do sd card remove and plug it back i am seeing a huge error on terminal

[ 83.160000] mmcblk0: retrying using single block read
[ 83.160000] mmcblk0: error -110 sending status comand
[ 83.180000] mmcblk0: error -110 sending read/write command, response 0xb00, c
[ 83.180000] end_request: I/O error, dev mmcblk0, sector 6688
[ 83.220000] mmcblk0: error -110 sending status comand
[ 83.220000] mmcblk0: error -110 sending read/write command, response 0xb00, c
[ 83.240000] end_request: I/O error, dev mmcblk0, sector 6689
[ 83.250000] mmcblk0: error -110 sending status comand
[ 83.250000] mmcblk0: error -110 sending read/write command, response 0xb00, c
[ 83.270000] end_request: I/O error, dev mmcblk0, sector 6690
[ 83.280000] mmcblk0: error -110 sending s

it keeps on populating, nearly 30 sec an udev rule gets an eject event, on removal of sd card ,

any one face this pls share your thought

patch would be helpful, i need a patch in kernel version, now i cannot move to new kernel

Hi Shashikant

kernel 2.6.35.10 is outdated kernel and not more supported by nxp,

support with it can be provided with Commercial Support and Engineering Services | NXP

Best regards
igor
