I must have been replying when you updated with the resets. Pressing the button effectively did the same thing as reseating the cards, but also call processing as well.
In the future you can reseat the DKSC16's by popping them loose using the white tabs at the top and bottom of the card. No need to power down for this, either.
As far as resets go, you could look in the other error logs to see the last time the system reset. If it was a while ago I wouldn't be too bothered by todays events, but I would do a backup.
In the future if you run into this try reseating the DKSC16+'s first. There is a DSP upgrade to correct no DT for older 16+ cards.
