Ubuntu – SD card not mounting with: mmc0: error -110 whilst initialising SD card

mountsd cardusb

I have card Sandisk SDXC 128 GB EXTREME PRO 95MB/s C10 V30 UHS-I U3.
It is working on Windows/Mac and my Fujifilm camera.

On my laptop (tested also on other laptops with Ubuntu) I got error:

mmc0: error -110 whilst initialising SD card

Details:
Dell Precision 5520, lsusb do not list this card. Card not visible in drives. Ubuntu 18.04.2 LTS

$ uname -a

Card formatted with exfat, but I have drivers for this filesystem installed.

Best Answer

There is a discussion at kernel.org about this topic. The reason has to do with the module rtsx_pci and the low voltage interface (LVI).

There is a patch available (2019-08-27, at the bottom), to be tested.
