This tells me, that already in the first iteration the eigenvalues are
completely wrong. You should not have a "band" from -9 to -5 Ry. This is
an almost dispersionless 3s state.
Most likely you find in the scf file even other problems
like "eigenvalues below XX Ryd", QTL-B's,....

Possible cuases I can only guess:

Has the symmetry been changed by symmetso ?
If yes, maybe it did not transfer the CLM's properly.

Run symmetso, but the try to restart with   x dstart -c (and -up/dn)
Are the bands then ok ?

If not, check with nn for proper distances,....

I'll be gone on vacations soon, so I cannot give any further help.
Contact me, if your problem still persists in 3 weeks.
