Description
Currently on Arch Linux after they shipped an update to the linux-firmware set (20170217.12987ca-1), there's been reports of various issues ranging from power management failing to in my case (AMD Radeon RX 460) Xorg failing to work at all (it either blinks and goes back to a frozen VT as the GPU hangs, or the GPU hangs on a full-screen corruption of some kind.) This is broken on both kernel 4.9.11 and 4.10 in my testing, on Xorg 1.19.1. The system still responds to SSH connections, but fails to shutdown properly if attempted over that.

I've traced it back to a specific commit to linux-firmware, 7a110b85a46d7f884f4ac712ff52e02ed57234bd, https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/commit/amdgpu/carrizo_ce.bin?id=7a110b85a46d7f884f4ac712ff52e02ed57234bd, pushed to the git repo on 2-17-17, which updates a large subset of the firmware images used by AMDGPU. Seeing as how this is a binary file set, I'm really not sure how to proceed from here in testing it to give any more useful information here.
Apologies if this is the wrong place to report a firmware issue, but I was unsure where to file it otherwise.
