Got a gpf dump with amdgpu_atomic_commit_tail, confirming it's the same bug. 
Still a couple bisect steps to go, but the EFI candidate's out now, leaving
only three (plus mediatek and nouveau, and an amdgpu that says it was doc fix
only), and the current round is testing between 406 and the 6bf/17f pair so I
should eliminate at least one of the three this round:

4064b9827
Peter Xu
mm: allow VM_FAULT_RETRY for multiple times

6bfef2f91
Jason Gunthorpe
mm/hmm: remove HMM_FAULT_SNAPSHOT

17ffdc482
Christoph Hellwig
mm: simplify device private page handling in hmm_range_fault
