We are on 8.2.151.0 on our 8540s and have not had any issues. Granted, we are also not using HA in our current design.

Cisco wireless engineers promised us code by the end of July that will address that issue. On 7/9/2018 1:15 PM, Swartz, Pola wrote: 8.5.131 code is available now.

The version of 8.5.131 coming later this month is where you'll want to be. Specifically, one of the fixes in the version of 8.5 coming later this month deals with HA issues.

Here recently we started noticing the HA unit on two of the pairs was in maintenance mode. We rebooted the controllers and they seem to have stayed in a continuous boot loop. We restarted one of the controllers to its emergency code (8.2.166) and it rebooted correctly without any issues, disabled SSO mode, rebooted back into 8.5.120 with no issues. We enabled SSO again and immediately went back to having boot loop issues. Is anybody else seeing this issue?
