Hmm, OK, I'm running a snapshot development from a week or two ago

 CP2K| version string:                    CP2K version 2.7 (Development 
Version)
 CP2K| source code revision number:                                 
 git:8a8c4da

please check whether you can run the XAS regtest I tried above. If that 
works then please post a full working example that shows the problem.
