1 I can't actually send from the machine so its hard to include stuff. I'm
2 not looking for a solution, just things to try.

4 I'm on kernel 4.9.16-gentoo
5 GPU is Turks XT (Radeon HD 6500/7670)
6 Kernel is setup according to the gentoo radeon guide, I compared it to
7 4.4.6 kernel, which has been working for months. Booting off that older
8 kernel doesn't change anything, so it can't be the kernel.

10 These are a manual transcript of selected Xorg.0.log errors
11 open /dev/dri/card0: No such file or directory
12 Device (s) detected, but none match those in config file
13
14 The /dev/dri directory does not exist. If it's created by udev, maybe I
15 have a udev problem?

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