Symphony OutputInterface failed to write

[dfelton]

This one is interesting... Something must have crashed as the machine was not displaying anything to the monitors but a black screen to one (the other turned off as it didn't register any incoming signal).

Restarting the machine didn't help...

After a sudo dnf update (noticing a new Kernel version as part of it), followed by downloading the latest NVidia driver, setting the machine to multi-user.target, and installing said drivers, the display monitors were working once again as expected. Oddly, during restarts not even the motherboards boot screen showed.

Anyhow, when (something regarding graphics) crashed, symphony then failed to write during an output attempt with OutputInterface. This caused an emergency shutdown as this was not something that had been handled yet.

Question in this scenario, is what to do about it? I'f hate to wrap every $output->writeln() in a try catch...
