It's probably better to read the spec to get clarity on these corner
cases, but it wouldn't surprise me if there were a scenario where a
receiver sends an ACK but then fails to complete a request
successfully, maybe because a bus error occurs while writing the data
to memory or something like that.

Yes, libibverbs and all drivers should follow the IB spec and always
generate a completion for all requests that complete with an
unsuccessful status.
