soft reboot again (Archeops 8 + Mac12). Array 2 is very noisy. We tried reducing the input power but it didn't help.

We have only a bit more than one hour left and we are reluctant to wake up Martino on Saturday early morning: we let next program start earlier than planned.

No: it works again ! Juan did one more soft reboot of crate 2 and this time it solved the problem.
