Is the engineering code you are running, the same MR5 code that is due to be released soon?

A "Kernel Panic". AP loses its mind. Very prevalent on the new stuff, to a much lesser degree affects "older" stuff. Sometimes the reset fixes it. Sometimes not. We doubled down on 1810's and 2802's. Bugs galore. Which are actively being fixed-to be fair. We are running on engineering code and HUGE improvements have been made. Soon, I think/hope, it will be rock solid.

We also run a half dozen 5520s with 8.2.141.0 and they have been running solid with around 1k APs each and upwards of 10k clients. We do not however run anything but 2600, 3600, 2700 and 3700 APs. The only issue I have seen that I don't understand well yet is related to some APs losing the minds during network interruptions. The APs will appear up from CDP neighbor information, but will have lost their name and will not connect to their configured primary or secondary controllers. A power cycle will often recover the AP, but not always. I believe that issue started with 8.2. Thank you.

However we have recently purchased a batch of 2802i access points whose minimum supported version is 8.2.110.0. I was looking to the group for their recommendations on a stable version of code which will support our new 2802i access points.
