So the error is coming from nvcc. The edm::Ref stuff gets included via

cmssw/DataFormats/HcalDigi/test/test_hcal_digi.cu

Line 11 in 86e051b

#include "DataFormats/HcalDigi/interface/HcalDigiCollections.h"

cmssw/DataFormats/HcalDigi/interface/HcalDigiCollections.h

Line 4 in 86e051b

#include "DataFormats/Common/interface/SortedCollection.h"

cmssw/DataFormats/Common/interface/SortedCollection.h

Line 31 in 86e051b

#include "DataFormats/Common/interface/Ref.h"

Thinking a workaround, on quick look it seems to me the #include of Ref.h in SortedCollection.h might not be necessary.
