Well, it was working fine for about a week. I have the RTL8192CU driver for wifi and use the RPI camera with motion for recording. I shut it down and restarted it and it started panicking at boot, after initializing the wifi. I pulled the wifi adapter and it would stay running and start crashing again as soon as I reinserted and booted with wifi.
I took an RPi B+ I had, connected everything and it booted and worked fine. No crashes. So, I did an aptitude safe-upgrade and rebooted. Everything continued to work so I put it all back on the RPi 2. So far, so good. No crashes. I'll continue to monitor it. It's still running motion with the camera. I have a very fast class 10 32gb memory card. It's one I've used with my Gopro Hero4 Silver.
I'm not overclocking and have not overclocked this RPi2.
I'm using a 2.4a power adapter.
