http://wiki.gromacs.org/index.php/Errors#LINCS_warnings tells you a bit
about this situation. There's some useful advice on alternatives for
system preparation here
http://wiki.gromacs.org/index.php/Steps_to_Perform_a_Simulation. In
particular, you may wish to see if you can do EM and simulate in vacuo.
Also starting your first MD run with position restraints is normally a
good plan.

They look OK to me.
