Realtek card reader does not work with rtsx.ko, stalls keyboard

[probonopd]

Describe the bug Realtek card reader does not work with rtsx.ko, stalls keyboard.

• Inserting card is regognized in dmesg, but lots of error messages in dmesg
• Removing card freezes USB keyboard for a while, but not USB mouse (strange!)

To Reproduce Steps to reproduce the behavior:

1. insert SD card into card reader
2. Add to /boot/loader.conf: dev.rtsx.0.inversion=1 - seemingly no change in result

Expected behavior Cards inserted into the card reader work.
