Kernel now has two possible kernel modules for a lot of the radeon |
| 2 |
cards, "radeon" and "amdgpu" . Don't remember the differences, google is |
| 3 |
your friend. "amdgpu" in 4.9 supports more cards than it used to. Rather |
| 4 |
prominent in the linux-4.9 announcements. Are you now (automatically? ) |
| 5 |
loading amdgpu whereas you maybe used radeon before? . |

Both modules, and the drm module, have options for verbosity. Turn them |
| 8 |
on and compare boot-logs from 4.8.14 and 4.9. Most likely you'll spot |
| 9 |
where it goes bad. |
