I have seen something strange today. The customer has had three R71.10 boxes, two UTM-1s and Smart-1. All with original factory images, no funky business.
We have made a routine upgrade via WebUI to R71.30. All three appliances failed to reboot after being "successfully" upgraded. They were stuck with "loading" messages on LCD screens.
We only could boot them after shutting them down with power switch.
I have checked all forums I know and SK DB for this kind of failure I did not find anything relevant. Did you see this kind of issues, guys?
