Re: [gentoo-amd64] Radeon driver not working (solved)

[Daiajo Tibdixious]

It looks like while cleaning up I de-installed linux-firmware, found this
by looking at dmesg. Reinstalled the firmware & all good now.

not looking for a solution, just things to try.

I'm on kernel 4.9.16-gentoo
GPU is Turks XT (Radeon HD 6500/7670)
Kernel is setup according to the gentoo radeon guide, I compared it to
4.4.6 kernel, which has been working for months. Booting off that older
kernel doesn't change anything, so it can't be the kernel.

These are a manual transcript of selected Xorg.0.log errors
open /dev/dri/card0: No such file or directory
Device (s) detected, but none match those in config file

The /dev/dri directory does not exist. If it's created by udev, maybe I
have a udev problem?

Are you expecting people here to guess your hardware configuration,
kernel configuration, debug messages, etc?
