We've got about as much chance of guessing what's wrong as your car
mechanic has if you ring them up and say the car doesn't work :-)
You'll need to tell us more about what you're doing - what command,
general nature of the input, etc.
Having said that, gromacs will only do the above when you are running
code that tests for things like sse/sse2/3dnow hardware support without
catching failure properly. I would not think that running pdb2gmx does
such a test... however, if so, it suggests you are running an executable
that wasn't compiled for your execution hardware.
