I can't provide further insight but I'm interested if this is possibly the cause for the general issues people are having with the SD card reader on Lenovo Miix 320 devices. Those issues described in posts like https://vincent-ventures.com/2018/12/arch-linux-on-lenovo-ideapad-miix-320/ https://esc.sh/blog/linux-on-lenovo-miix-320/ are (1) black screen when booting with an SD card installed and (2) when inserting an SD card after booting it shows up but upon trying to access it the screen turns black until the card is removed again. I can confirm (1) on my Lenovo Miix 320-10ICR with kernel version 5.2.11. I can also confirm that only SDXC cards are affected, SD and SDHC cards work as expected. Thank you for the bug report. I've just posted a fix for the black screen on Lenovo Miix 320-10ICR when using USH microSD card issue upstream. See the commit message for technical details about the problem (if you are interested): https://lore.kernel.org/linux-mmc/20200306143100.164975-1-hdegoede@redhat.com/ Hopefully this fix will get accepted upstream soon. |
