  Let F be a Henselian valued field with char(F) = p and D a semi-ramified,
"not strongly degenerate" p-algebra. We show that all Galois subfields of D are
inertial. Using this as a tool we study generic abelian crossed product
p-algebras, proving among other things that the noncyclic generic abelian
crossed product p-algebras defined by non-degenerate matrices are
indecomposable p-algebras. To construct examples of these indecomposable
p-algebras with exponent p and large index we study the relationship between
degeneracy in matrices defining abelian crossed products and torsion in CH^2 of
Severi-Brauer varieties.
