I've had this problem for a long time on Debian Wheezy up to the past several releases of Ubuntu. Even running mainline kernels don't seem to fix. Currently on Ubuntu 13.10 3.14.0-031400rc1-generic
Today, I finally got some stability by adding/modifying the line to: system-ca-certs=false AND then changing the rights to read only on the connection.
 chmod -w <ssid>
Not sure how long this will work, but it's survived several suspends/connects/disconnects much better than before.
