GPIB trouble: under Debian-10 it may happen that the GPIB module is not loaded properly after reboot. Tango servers communicating via GPIB will not work. The problem has been studied intensively but so far it was not possible to fix it.
User action: if one of your GPIB-related Tango servers gives problems, check
dmesg | grep -i gpib
for 'gpib: no gpib board configured on /dev/gpib0'.
If so, execute
sudo /usr/local/sbin/gpib.sh
