Public bug reported:
Upon attempting to use my SD card reader in my Thinkpad W541, I am no longer
able to read cards. Ubuntu 17.10 worked OK, but 18.04 does not. I have since
done a fresh install and it still does not work. I have tried some workarounds
including:
sudo rmmod sdhci sdhci_pci sdhci_acpi
sudo modprobe sdhci debug_quirks2="0x4"
sudo modprobe sdhci_pci
including: "0x10000", and "0x80000000", but none of these are working.
I still cannot get my SD card reader from O2 Micro to work.
The logs I am getting when inserting an SD card are the following:

Any help is welcome, but I am submitting this as a bug, because it seems
to be affecting all of my laptops with O2 Micro's as well, not just my
Thinkpad W541 I am writing this on right now.
