I can hardly answer this question. I got a new notebook and installed 17.10 (beta) on it. I could use the SD card initially. Then after official launch, all external devices caused system hangs during mount.
After a restart, the SD card could be mounted as sdc With 18.04 the device drivers (sdhci and sdhci-pci) are not loaded and the device does not get recognized. Even when loading the modules the medium does not get mounted. As this is my production machine and I am using it heavily this semester I am rather reluctant to experimenting with different kernels (I am not sure but the disability to mount harddisks after suspend to RAM came in at the same time as I installed a premature kernel). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1768225 Title: SD card not mounted Status in linux package in Ubuntu: Incomplete Bug description: Ubuntu 18.04 after fresh install: HW: Macbook Pro Retina 13" SD cards are not recognized nor mounted. The sdhci driver is not loaded by default. Manual loading of sdhci and sdhci-pci does not make the SD card mount or be recognized (loading the driver is acknowledged in the syslog) Adding a configuration file under /etc/modprobe.d with options sdhci debug_quirks2=4 does not remedy the situation.
