First of all many thanks to YL_Intel and ak6dn.

Today we saw the same error on a second board in a completely different test setup (but the same type of board). Therefore I would say that it isn't a broken IC. OK, maybe both boards are broken but this is very unlikely.

I'm in touch with the manufacturer, but he is assuming there is a software problem.

Is it possible to reset the EPCQL with a special command? I haven't found anything like this in the datasheet yet.
