excerpt from dmesg loading radeon/amdgpu

Linux 4.10 brings support for amdgpu on si chipsets, but when after enabling the kernel options my screen froze at boot time (during udev-trigger).

i started in interactive mode and found that the system is missing the file "radeon/si58_mc.bin".

from dmesg:
[  836.667254] [drm] Loading pitcairn Microcode
[  836.668858] radeon 0000:01:00.0: Direct firmware load for radeon/si58_mc.bin failed with error -2

after manually downloading the missing file from https://people.freedesktop.org/~agd5f/radeon_ucode/si58_mc.bin and copying it to /lib64/firmware/radeon the system boots as expected

graphics card: amd r7 370
linux versions tested: 4.10.1, 4.10.2, 4.10.4

Thanks for the report.

I'm not sure why we created these packages. They're just specialized versions of sys-kernel/linux-firmware.

Please install sys-kernel/linux-firmware instead.

I'll remove sys-firmware/radeon-ucode and sys-firmware/amdgpu-ucode to prevent this sort of thing from happening in the future.

i removed radeon-ucode, and the missing file is present in linux-firmware, so works for me :)

I'm removing these packages per bug 614218. You're happy with linux-firmware, so I'll mark this as WONTFIX.
