I'm running CB2 board as home server for a long time and after recent upgrade I've got an issue with LXC container.
LXC container has "Ubuntu" inside and provides TOR functionalty + access point via connected USB wifi. USB adapter passed to container like this:
lxc-wait -n tor -s RUNNING
lxc-device -n tor add wlan0
I'm not using it recently, but recently I found, that after connection to AP nothing happens (no internet, DNS servers are IPV6 :)) and host system (CB2) is completely frozen.
After reboot I've connected via SSH and retried to connect to access point - again freeze, and screen is populated with this:

I'm pretty sure, that it stared with one of recent upgrades. Unfortunately I utilize "torred access point" not really often, so cannot tell, which upgrade exactly caused this. It worked like charm in April :).
Since such setup (with LXC + bypassing network interface) is not really common, I understand, that it may not be not fixed in visible period of time :(.
So 2 questions :
1) Did anyone encountered something similar or just something LXC-related with recent kernel and any chances to fix this ?
2) How I can downgrade kernel to previous version (looks like after this I can freeze kernel update via this new utility) ? Where packages are located and what is correct procedure ? (Sorry if it was already asked).

P.S. dmesg attached just in case.
