For the pleasure of PVDIS parasites only ...

I think the FADC is working now on ROC2. I will leave it disabled after
testing because the FADC causes deadtime.

Main change was as follows (< is new; > is old)

548d547
< variable d1,d2
599,602c598
< d1 = sis3320GetData(SIS3320_ADC_ID, ichan, i, 0);
< d2 = sis3320GetData(SIS3320_ADC_ID, ichan, i, 1);
< *rol->dabufp++=(d1<<16)+d2;
< /* *rol->dabufp++=mem_loc[read_pointer+sub_index]; */
---
> *rol->dabufp++=mem_loc[read_pointer+sub_index];

Other things tried which did not matter
1. Use identical kernel version as ROC4
2. Use same order of spawning tasks in boot file as ROC4.

The sis3320GetData function should work. However, Kai should check
the data to see if he can produce a pulse. All I can say at this point
is the DAQ runs stable (with all 8 channels) and I see pedestals.
