Chromebooks that are running v53.0.2785.154 not exhibiting any problems. Chromebooks running v59.0.3071.91. are looping at boot (see attached video). If they are moved to a location where they disassociate from wifi during the boot cycle they may come up to a login screen. If you login on a device and turn off wifi, it will allow you to move to the original location and reboot successfully. After rebooting, as soon as wifi is turned back on the device reboots immediately and returns to the loop state. Device was successfully managed when on v53. First, sporadic reports were on 9/12 one day after devices were first connected to network after being handed out at our middle school. Devices were purchased in Dec. 2016, and enrolled in March/April 2017. They were stored until start of school year deployment.

Observing the same problem with Dell Chromebook 11 models 3120 and 3180. User turns on Chromebook, loads login screen, ChromeOS attempts wireless connection, crash. Repeat. Seems like an obscure incompatibility with Extreme Wireless causing the panics, but they shouldn't be happening in the first place. Rebooting the AP fixes the issue temporarily.
