Here's the .config of the kernel which crashed when loading the radeon |
67 |
microcode: http://servbox.moshbear.net/r9k-3.3.6-pf-.config.txt |
68 |
|
69 |
On 3.3.6, dmesg did tend to fill up with "uvesafb: mode switch failed |
70 |
(eax=0x34f, err=0). Trying again with default settings." |
71 |
|
72 |
Also, I'm unsure how use of userspace modeseting contributes to X's |
73 |
drm code confusing an opcode for a pointer. |
74 |
|
75 |
xorg.conf is blank since X's hardware detection is sufficiently |
76 |
functional to not require a xorg.conf. |

I use ~amd64 because I like having everything be recent. Otherwise, it |
85 |
tends to feel a bit like a fast version of debian. That, and 99.9% |
86 |
functionality is enough. I've been able to fix almost all issues that |
87 |
arise by means of google - this one is simply proving to be tricky. |
