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.

  • I confirm the same issue on Linux Debian 10 with a brand new Sandisk SDXC Extreme Pro 128GB 170MB/S. Just tested and on Windows, but replies with "error -110" on Linux 4.19.0-4-amd64 on a Lenovo Thinkpad. – user947518 Apr 22 '19 at 16:19
  • Same problem here. I have a handful of brand new "SanDisk Ultra Plus" and "SanDisk Extreme Plus"; the Ultra work perfectly fine, but the Extreme do not work on Linux. The block devices don't appear, and I get the same message, mmc0: error -110 whilst initialising SD card. The cards work fine in cameras, BlackMagic recorders, and on the same machine using Windows; but they don't work on any on my Linux machines. I believe the Linux MMC driver is supposed to configure the port in a particular way (different voltage? Frequency?) but fails to do so; but that's just a wild guess. – jpetazzo May 29 '19 at 19:28

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.
