clinfo output

I'm not sure whether this is a mesa bug, so if it's not: I'm sorry
Anyway, the problem:
I have 2 GCN cards in my system, a 7700 and a R9 nano
I'm using both with amdgpu on linux-4.13.0-r4
clinfo attached.
My program causes a GPU fault on the 7700 when reading from a buffer.
dmesg part attached
this problem does not occur on the CPU or the R9 nano card
GDB backtrace of thread calling the clEnqueueReadBuffer attached

If this is a known bug, or not yours, I'm sorry
