Entity framework and SA 12 - have to delete foreign keys to create EDM

Hello,

We have a problem similar to this one.
We have a DB with ~400 tables and ~1300 foreign keys. All tables are empty. Generation of Entity Data Model succeeds only when foreign keys are deleted. When foreign keys are present, the process seems to never end (even when trying to map only one table with no relations to other tables). DB server CPU load is near 100% almost all the time (from beginning until killing the mapping process).

It works fine with a much lesser DB on the same server (only 40 foreign keys).

DB server - Win XP 64 bit (test server), SA 12.0.1.3436.
We tried the workaround mentioned in the link above (DB server on Win 7) but with no success.
We also have applied the latest EBF (3726) to the client side but that did not help too.

Is it a bug or are there some known restrictions?
Thanks.

Maybe you should give Sybase a sample db so that they can try to reproduce it.

I also have the same problem. I've even tried using Typed DataSet and DB server hangs with 100% CPU when I try to configure an existing TableAdapter. With Entity Framework I'm able to create a model based on views, but as soon as I try to add a table, the DB server hangs forever.
