I was rummaging through my freezer collection. I have a roll of PanF of unknown age. I recall hearing problems with old PanF but no specifics. SHould I shoot it and if so what E.I.?
I think the well known problem is with latent images, so the trick is not to wait too long after using it to develop it. I'd expect the film to last pretty well in a freezer. Hopefully someone else will chime in if that's not right ( I'm just parroting what I've read... not from personal experience! )

You should be okay shooting at box speed if frozen but don't expect to see any images on the rebate. Once the film is a couple of years of age, the imprints on the rebate will have faded and most likely disappeared. I am just about finished with a bulk roll that has not yet expired and I have a difficult time making out any marks on the edges. A word of caution: once exposed, develop immediately! Waiting a month will make a big difference on how much image you will retain. This film indeed does suffer from the 'latent image fading' problem.
Movie film with latent images found in Antarctica many years later was developed and ok, although I have no idea about how they went about processing film. Excessive heat is much harmful.
