Thanks, Joseph. Bug exists on mainline 4.6.0-040600rc7.201605081830.
In first test it completely failed to mount card, spaming with errors:
May 9 16:05:53 dev-laptop kernel: [ 103.547966] mmc0: error -110 whilst
initialising SD card
May 9 16:05:57 dev-laptop kernel: [ 107.655738] mmc0: error -110 whilst
initialising SD card
May 9 16:06:01 dev-laptop kernel: [ 111.763336] mmc0: error -110 whilst
initialising SD card
Eject/re-insert was required to mount card and perform second test:
copy/md5sum test fails with "mmcblk0: error -110 sending stop command,
original cmd response 0x900, card status 0x900" errors and corrupted
data.

Title:
rtsx_usb module for Realtek Semiconductor Corp. RTS5129 Card Reader
Controller: mmc errors and read data corruption
Status in linux package in Ubuntu:
Confirmed
Bug description:
RTS5129 Card Reader has issues with rtsx_usb module on kernels >=3.16
(since kmod-staging rts5129 module replaced with rtsx).
Copying files from FAT32 SDHC memory card produces error messages in syslog:
May 9 05:39:15 dev-laptop kernel: [ 134.762713] mmcblk0: error -110 sending
stop command, original cmd response 0x900, card status 0x900
May 9 05:39:15 dev-laptop kernel: [ 135.427035] mmcblk0: error -110 sending
stop command, original cmd response 0x900, card status 0x900
May 9 05:39:16 dev-laptop kernel: [ 136.030041] mmcblk0: error -110 sending
stop command, original cmd response 0x900, card status 0x900
Also these errors indicate that copied files are corrupted - md5sum
shows different checksums for copied file after each "insert card/copy
file/check md5sum/eject card" cycle (actually you can skip "copy file"
step and run "check md5sum" step directly with file on mounted memory
card filesystem).
Running sudo badblocks -n /dev/mmcblk0 produces same error messages
and prints a lot of random block numbers.
Hardware:
- dell inspiron 7720 laptop (a few different RAM modules and HDD drives used
for testing);
- Realtek Semiconductor Corp. RTS5129 Card Reader (ID 0bda:0129);
- Transcend 32Gb SDHC Memory card Class 10 UHS-I.
