Hi Ian, I'm running into the same problem. I updated the source on a RPI2 today, build a new kernel (with modules), installed it, manually copied = /boot/dtb/rpi2.dtb to /boot/msdos/ (which is mounted) and rebooted. The dtb files have the correct date, but the kernel panics. Do I need to = copy more? Thanks for your help! Best regards Michael >=20 > -- Ian >=20 >> The file has been moved.
