I can't reproduce on my laptop with my card readers (rtsx_usb) on hirsute and even newer kernel. Could you try some other card readers (ex. USB interfaced card reader) and check if the same thing can be reproduced?
And can you please turn on the dynamic debug for the module "rtsx_pci" and "rtsx_pci_sdmmc" and post the dmesg here? 1. sudo su 2. echo "module rtsx_pci +p" > /sys/kernel/debug/dynamic_debug_control 3. echo "module rtsx_pci_sdmmc +p" > /sys/kernel/debug/dynamic_debug_control Then unplug/plug the SD card and post the dmesg output here.

If I then unmount it, remove it then re-insert it I get this in the system ,og: [ 194.673108] mmc0: card e624 removed [ 205.462065] mmc0: cannot verify signal voltage switch [ 205.567479] mmc0: error -84 whilst initialising SD card and the card cannot then be used. It was OK in groovy. It's failing in hirsute.
