Hi Olliver,
well as long as you don't explicitly disable the support for the older
hw generations the R7 250 is still supported and should still work
perfectly fine.
What you see here is basically some reference counting issue, most
likely in the display code.
Question to Alex and Harry is CIK already using DC or the classic
display code? If it's DC then it looks like we either miss unpinning a
BO or grabbing a reference to a BO.
Regards,
Christian.

Sorry for just dumping this here, but for those that think this is
important, just rebooted after a weird btrfs crash (remounted r/o, no
dataloss it seems), probably a new kernel, and got duped with the
following. Things 'seem' to work fine however. I don't even know how
or where to google for this one.
My graphics card is I think the R7 250, or some old beast like that,
and I also know i'm probably shouldn't be using amdgpu on this oldtimer?
