Your stacktrace indicates that you don't use the latest version of PDMats. PDMats 0.11.3 defines isposdef and hence you should not end up with the fallback definition in LinearAlgebra.

I checked and I can reproduce the issue with PDMats 0.11.2. However, as expected, it is fixed in PDMats 0.11.3:
(@v1.6) pkg> activate --temp

trueSince it's fixed in the latest release I'll close the issue 🙂
