As mentioned on IRC, going forward there will only be a single channel 18-pi.
Also, since this problem is resolved in the 5.x kernel, I'm going to mark this bug as resolved. If someone needs this with the 4.15 kernel or with core16, please open a new ticket and we'll evaluate it. ** Changed in: linux-raspi2 (Ubuntu Bionic) Status: New => Fix Released -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-raspi2 in Ubuntu. https://bugs.launchpad.net/bugs/1823655 Title: Second SD card on RPi3 CM3 on Ubuntu Core 18 does not work Status in linux-raspi2 package in Ubuntu: In Progress Status in linux-raspi2 source package in Bionic: Fix Released Bug description: As suggested in following thread; https://forum.snapcraft.io/t/second-sd-card-on-rpi3-cm3-with-ubuntu- core-18/10465 a bug report.
