Comment (by darchon):

 I've enabled tracing code for interface reading code, and I get a little
 more detail:

 {{{
 Starting fork { Dict fun Control.Applicative.$fAlternative[]
 Starting fork { Declaration for $fAlternative[]
 Loading decl for Control.Applicative.$fAlternative[]
 updating EPS_
 Considering whether to load ghc-prim:GHC.Types {- SYSTEM -}
 Reading interface for ghc-prim:GHC.Types;
     reason: Need home interface for wired-in thing []
 updating EPS_
 attempting to use module ‛ghc-prim:GHC.Types’ (libraries/ghc-
 prim/./GHC/Types.hs) which is not loaded
 }}}
