With or without crossfire, I encounter the problem, and the graphic |
| 31 |
card in slot number one is always the one taking over. |
| 32 |
|
| 33 |
Also, I already set up a console over serial port, but nothing gets |
| 34 |
out when the system hangs. That's why i am now at the point of running |
| 35 |
the kernel under GDB. Also, I want to say that the problem does not |
| 36 |
occur on boot phase at all, everything goes just fine until I activate |
| 37 |
any other power profile than 'default' one on the radeon card using: |
| 38 |
# echo '(low|mid|high)' > /sys/class/drm/card0/device/power_profile |
| 39 |
|
| 40 |
Then, once power management activated, the system randomly hangs |
| 41 |
*AFTER* a various amount of time, requiring a hard reboot. |
