Same problem here, I'm currently using 4.5.0-rc4-mainline with the Realtek Semiconductor Corp. RTS5129 Card Reader Controller on Arch Linux. The problem appears just on Linux, and I have fixed it a while ago, until I format my pc and installed Arch. Unfortunately I don't have the solution anymore (see http://unix.stackexchange.com/questions/257033/rts5129-card-reader-with-ubuntu-15-10) since the user who has commented actually deleted his account.
This happens when I put on a class 10 micro sd card with an sdcard adapter in my Acer Aspire V17 Nitro [ 132.789797] sd 4:0:0:0: [sdc] tag#0 UNKNOWN(0x2003) Result: hostbyte=0x00 driverbyte=0x08 [
