We present new lattice investigations of finite-temperature transitions forSU(3) gauge theory with Nf=8 light flavors. Using nHYP-smeared staggeredfermions we are able to explore renormalized couplings $g^2 \lesssim 20$ onlattice volumes as large as $48^3 \times 24$. Finite-temperature transitions atnon-zero fermion mass do not persist in the chiral limit, instead running intoa strongly coupled lattice phase as the mass decreases. That is,finite-temperature studies with this lattice action require even larger $N_T >24$ to directly confirm spontaneous chiral symmetry breaking.
