Aparently the problem is already at the beginning when lapw2 tries to
calculate clmval. Maybe even in lapw1 proper eigenvalues could not be
found.

Set RKMAX=3 (to make it faster) and try again from scratch.
If it happens again, examin the scf1/output1/scf2/output2 files and
any messages in the dayfile.
