My 822 started freezing and rebooting after the update. I found that it happened when the phone was changing data connection protcols. It started regularly occurring on my drive to work when I passed two areas where LTE drops to wither 3G or Edge. I had previously noticed that I always either had an LTE indication, or no data indication at all. I subsequently checked my cellular phone settings and found two settings that caused these issues. My Mode selection was set to "Global" and my data roaming was set to "do not roam". I changed these settings such that the Mode is now "LTE and CDMA" and the data roaming is now set to "roam" - check that your VZW plan allows data roaming where you are using your phone...most plans do.
Since doing this on the 10th, I have not had a single instance of freezing/rebooting, nor a lost data connection. I now see the 3G and 1x indicators in non-LTE areas, where I would lose data altogether before. I highly suspect that when the cellular settings are not as I noted above, that there is a software glitch causing issues when the phone tries to negotiate between the various data connections; i.e. during the hand offs. I could actually cause my phone to crash when I was attempting to start a stream in Pandora when passing through one of these non-LTE areas, and do so regularly. Check the settings in your phone and see if they are set the way mine were, and, if so, try changing them and see if it works for you. It's a simple check and change with no impact to you unless you leave the country.
There is a patch coming for this issues, according to VZW...specifically the loss of data connection and subsequent crashing.
