My personal opinion:
Jeff is in the AVALON scam too.
24 hours after he received it, he posts 6 real photos and some shit a kid can do with Photoshop, when he knows there are close to a million $$$ at stake.
It's safe to say we are going to ignore your personal opinion.
Why would somebody who is into the scam post critical reviews like
http://garzikrants.blogspot.ca/2013/01/avalon-asic-miner-review.html where he clearly explains he got paid BTC 25 to write a review?
Why would he post his concerns that the machine has various reboots that could be blamed on overheating?
Nevertheless, the unit has seen several cgminer restarts, and a few full machine restarts. Machine restarts seem to happen every 4-6 hours. Even ignoring more obvious means of restart detection (login and look at uptime, or ping-monitoring etc), a restart is a clearly audible event: At startup, the fans race at full speed for a few seconds, before "calming down" to a more moderate pace.
One of the temperature monitors consistently reads close to 50, so it is possible or even likely that temperature is playing a factor in these restarts. Yifu stated that this machine has several failsafes, where it will restart upon abnormal events.
