The following might be related, if so great, if not sorry for the spam.
We had problems with MIDAS/CAEN_A3818 until two things happened:
1) CAEN found the root cause of a problem, as the A3818 and MIDAS both
used unix alarm signals, resulting in clashes. CAEN modified the
A3818 driver to have a "no alarm" option.
2) after downloading the modified driver, edit src/a3818.c to #define
USE_MIDAS 1 somewhere near the top.
Hope this helps,
