mirabox kernel panic with upgrade to linux-3.14.2-1

[branch]

Hi, I was wondering if anyone else is seeing this problem with the upgrade from linux-3.14.1-1 to linux-3.14.2-1 on mirabox. After upgrading I get kernel panics like the following after 5-10 minutes of uptime with moderate network activity. Reverting back to linux-3.14.1-1 seems to restore stability.
