--- Comment #5 from Felix Kuehling (felix.kuehling at amd.com) ---
There are two patches that didn't make it into Linux 6.6 that reduce the 
stack size in kfd_topology_add_device. Can you check if those fix the 
problem?

     drm/amdkfd: drop struct kfd_cu_info

     I think this was an abstraction back from when
     kfd supported both radeon and amdgpu.  Since we just
     support amdgpu now, there is no more need for this and
     we can use the amdgpu structures directly.

     This also avoids having the kfd_cu_info structures on
     the stack when inlining which can blow up the stack.
