I think the ETMX slow machine might be dead. All of the regular FE readbacks are fine, and the c1iscex FE computer looks fine, but the slow readbacks are all whited out.
I turned off the damping loops for ETMX, since I don't have access to the watchdog disable/enable switch. I guess checking this out will be task #1 for Monday morning.
For lack of a better idea, I keyed the crate. The computer came back up just fine, ETMX is happily damped again.
