Has anyone succeeded installing open-source mesa driver for RX 480 in Ubuntu 16.04?
According to the Phoronix articles, the free driver should be similar or even better vs amdgpu-pro (binary blob) http://phoronix.com/scan.php?page=news_item&px=Radeon-RX-480-Drivers
Using default kernel 4.4, the card was working using software render (llvm-pipe). After installing 4.8 or 4.9 kernel from ubuntu-kernel ppa (http://kernel.ubuntu.com/~kernel-ppa/mainline/), i got kernel panic or just blank screen (not responding to anything)
I am also using Oibaf PPA https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers
I did download
polaris10_mc.bin and placed it
/lib/firmware/amdgpu but it didn't help
