foxbat, thanks for posting this!

Well, isn't THAT interesting! Requested size is ALMOST, but not quite, 160 MB, while what the sub-allocation manager has left is 1 MB.
Sounds like we have an overrun in amdgpu_vm_bo_update_mapping() while calculating how many bytes we need to allocate from the sa_manager.
