Hi folks,

In switching from 3.1-p8 to 3.3-p6, keeping the same ML ml-6.2.tar.gz, I get
indefinite preconditioner with the newer PETSc version. Has there been anything
substantial changed around how PCs are handled, e.g. in the defaults?

I know this request is pretty general, I would just like to know where to start
looking, where changes in PETSc might be clobbering the (supposedly same)
behavior of ML.
