Every newer version of bcmwl-kernel-source than 6.30.223.141+bdcom-0ubuntu2 causes complete Freezes on my System every few Seconds. Removing the wl module restores the system to its normal state. Compiling the latest version 6.30.223.248 from the Broadcom STA Source makes no difference as well as using the latest Mainline-Kernel. So some of the changes between 6.30.223.141 and 6.30.223.248 must be responsible.
Version 6.30.223.248+bdcom-0ubuntu0.1 installs without any Errors but as soon as the wl Module is loaded the Freezes occur. Dmesg shows nothing of note.

I'm experiencing a similar issue with the same chipset: only when connected to certain networks, the OS randomly freezes and then I'm forced to do an hard reboot.
The issue appears to be present in Ubuntu 14.04, 14.10 and 15.04.
