To the best of my knowledge, this specific (resume from suspend, intel_pstate, performance mode) issue has been fixed in the upstream kernel. However, I never understood this issue to be specific to battery mode, an interesting twist.
Note that there are other issues, and sometimes it is hard to separate the issues and they tend to cross contaminate these bug reports.
