I am running kernel v4.5 on an Merrii Optimusboard (Allwinner A80).

Messages like the following are written in 3 to 15 second intervals
while copying files to a micro SDHC card.

[ 1670.055412] sunxi-mmc 1c0f000.mmc: smc 0 err, cmd 25, WR EBE !!
[ 1670.061468] sunxi-mmc 1c0f000.mmc: data error, sending stop command
[ 1670.068250] mmcblk0: timed out sending r/w cmd command, card status 0x900
[ 1670.139125] mmc0: tried to reset card

Best regards
