is anyone facing a D3 that is rebooting by itself?
I have 2 D3 that are working fine, all chips are good and hashing however when I login to check, I see that it has been up for few hours, even-though I have never turned it OFF.
Cycle the firmware, make sure the temp is steady.
Check the logs after the reboot. If new firmware does not help, post the logs and some community member will likely help you out.
