The c1als model was pulling out some ADC0 connections that were no longer used for anything:

• ADC_0_1 --> sfm "FD" --> IPC "C1:ALS-SCX_FD"
• ADC_0_5 --> sfm "OCX" --> term
• ADC_0_6 --> sfm "ADC" --> term

The channels would have shown up as C1:ALS-FD, C1:ALS-OCX, C1:ALS-ADC.  The IPC connection that presumably was meant to go to c1scx is not connected on the other end.

I removed all this stuff from the model and rebuilt/restarted.
