Interesting. I've had no reliability issues with the ds9490r (on Linux anyway) prior. My plan was to try disconnect reconnect of the ds9490r and then swap out sensors, but it decided it wanted to run for another day without problems. I avoided this is the first place because it's inside of an enclosure. No kernel messages. I've checked every log I can think to.
I've since switched to an i2c chip which is testing well, but my beer fridge needs to stay cold.
