Fix: Import all the necessary patches (see the pull request below). How to test: 1) put the board in fastboot mode (see [1]) 2) generate a compatible boot.img: $ cat linux/arch/arm64/boot/Image.gz linux/arch/arm64/boot/dts/qcom/apq8096-db820c.dtb > Image.gz+dtb $ touch ramdisk $ python android/system/core/mkbootimg/mkbootimg.py --kernel Image.gz+dtb --ramdisk ramdisk --pagesize 4096 --base 0x80000000 --kernel_offset 0x8000 --ramdisk_offset 0x1000000 --tags_offset 0x100 --cmdline 'console=ttyMSM0,115200n8 root=/dev/sda1 net.ifnames=0 init=/lib/systemd/systemd ro rootwait rng_core.default_quality=700 panic=-1 fixrtc earlyprintk earlycon=msm_serial_dm,0x75b0000' --output bionic-snapdragon-db820c-boot.img 3) fastboot the board using the freshly generated boot.img: $ fastboot boot bionic-snapdragon-db820c-boot.img Regression potential: With new code there's always a degree of regression potential, but all patches (but one) were cherry-picked from Linus's upstream tree, and the only external one, came direclty from the qcom-lt 4.14 tree. 1: https://www.96boards.org/documentation/consumer/dragonboard/dragonboard820c/installation /board-recovery.md.html To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-snapdragon/+bug/1832012/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
