Please also attach the dmesg output from before the problem occurs, containing
at least all the amdgpu and TTM initialization messages.

Print fpfn/lpfn values in ttm_bo_mem_space_debug

Can you rebuild the ttm.ko module with this patch applied, and attach the
resulting dmesg output when the problem occurs again? It might shed some more
light on why we fail to evict a BO to GTT, even though there seems to be enough
space there.

There is no dmesg from before the problem occurs.
I will try the patch!

[Bug 106634] Failed to find memory space for buffer [...] eviction

--- Comment #7 from Michel Dänzer <michel@daenzer.net> ---
Actually, it seems clear that this happens because 1 GB of VRAM and 3 GB of GTT
are full with buffer objects. Unless this keeps happening even immediately
after closing applications / logging out and back in / restarting X, this looks
like a userspace issue (could be a leak somewhere).
