I'm trying to reproduce the bug using radeon and DRM stuff built as a |
| 33 |
module instead. Did you enabled power management too with the following: |
| 34 |
# echo '(low|mid|high)' > /sys/class/drm/card0/device/power_profile |
| 35 |
|
| 36 |
For me, as soon as I enable this, the system hangs randomly (meaning |
| 37 |
it can hangs right after enabling the feature or several hours later). |
