--- Comment #7 from Janpieter Sollie (janpieter.sollie at dommel.be) ---
hello, I have some other news about this bug (if anyone is still interested):
I rewrote the amdgpu-pro driver, as the amdgpu driver seems more complex, and I
took one step forward! this is my solution:
- unload the Cape Verde card with echo 1 > /proc/sys/pci/0000:41:00.0/remove
- load the driver, the driver loading finishes successfully
- rescan the pci bus: echo 1 > /sys/bus/pci/rescan
then the behaviour of amdgpu and amdgpu-pro are the same: the system reboots
after initialisation, even if I order it not to restart on panic.
can somebody tell me where I should look for Cape Verde initialization code in
the in-tree driver? I may be able to fix the initialization bug.

Thank you
