I have a Raspberry Pi 3 B running jessie 8
It has been stable, survived a few power interruptions over the years and always came back up with no issues. This time when power was disrupted the following symptoms occurred:
The MAC address changed on the wired NIC (eth0).
A different IP address was issued from my router and I can ssh into it with the new address.
I can still ping the original IP address but get connection refused if I attempt to ssh to it.
What would cause the MAC address to change, and why would I still be able to ping the old IP address?
ifconfig reports no address on wlan0 and I don't use wireless on this system.
