I am not sure if I am to raise a separate bug report but also the stock firmware linux-firmware-raspi2 (1.20151118+b70b451-0ubuntu1) xenial appears to be broken for RaspBerry Pi 3. The Firmware however appears to work for RaspBerry Pi 2.
As a test I was able to successfully boot my RPI3 using 3rd party PPA / firmware package from Ubuntu Pi Flavour Maker Team (https://launchpad.net/~ubuntu-pi-flavour- makers/+archive/ubuntu/ppa/+files/raspberrypi- bootloader_1.20160315-1~xenial1.0_armhf.deb) but I still needed to use an older Kernel suggesting both the current stock Kernel and Firmware are independently broken. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1611944 Title: Kernel / vmlinuz broken for RaspBerry Pi 3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1611944/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
