What is the cause of the [AP Restart: Kernal Panic] issue in R610 unleashed?

[young_joon_kwon]

Hello, everyone.

The AP is losing connectivity because logs from [AP Restart: kernal panic] continue to occur on the R610 Unleashed model you are currently using.

The symptom occurred at 6/21, and after the [heartbeat loss], the [Unleashed network change master] occurred in the log and the master AP changed.

Additionally, there was a power outage in the 6/9 building, and all APs were down.
The [kernal panic] log has been found since power outage and appears to be an issue caused by power failure.

Is there anyone who has the same issue as me issue?
Please share the solution to the issue.

Thank you.

I have had the same issue occur once in awhile.  It really started after I updated to 200.10 firmware so I am thinking it's related to that now my PoE switch.  What firmware are you running on your 610?

@rsullivan The R610 firmware is 200.7.10.202.94.
The firmware was also used at the time of the issue and occurred after the power outage.
Do you think it's not just a firmware issue, but a poe switch issue?
