The exact general solution to the Einstein equations in a homogeneous Universe with a full causal viscous fluid source for the bulk viscosity index m=1/2 is found. We have investigated the asymptotic stability of Friedmann and de Sitter solutions, the former is stable for m> 1/2 and the latter for m< 1/2. The comparison with results of the truncated theory is made. For m=1/2, it was found that families of solutions with extrema no longer remain in the full case, and they are replaced by
