Is this on an amd64 platform as well? Also I tried this on the 2.6.19-r2 kernel as well, same result.

It seems that now you need CBC support in the kernel (in Cryptographic options). I added it as advised in a thread in FGO and everything works as before.
thanks for the report, new warning added in cvs.
