SD card reader does not work

When I put a SD card into reader in my Acer aspire tc-885-ua92 laptop, I get following message from dmesg:

[   40.179688] mmc0: cannot verify signal voltage switch
[   40.623538] mmc0: tuning execution failed: -22
[   40.623542] mmc0: error -22 whilst initialising SD card
[   41.462547] mmc0: cannot verify signal voltage switch
[   41.905681] mmc0: tuning execution failed: -22
[   41.905685] mmc0: error -22 whilst initialising SD card

[   43.505253] mmc0: tuning execution failed: -22
[   43.505257] mmc0: error -22 whilst initialising SD card

I also tried to install rts_bpp but it does not help, even with blacklisted rtsx_pci.
When I blacklisted rtsx_pci I got absolutely nothing, not even the error in dmesg when I inserted  a  card.
