Note that this is related to the bcmwl package: the kernel works OK
until the 'wl' module is loaded, when it immediately crashes. This test
was run with the current bcmwl (6.20.155.1+bdcom-0ubuntu4; all of the
6.20.155.1 bcmwl packages cause the failure).
The associated bug is bug 1089114.
Additionally. Until 3.7.0-6 and the first bcmwl 6.20.155.1, all was
fine. On 3.7.0-6 bcmwl 5.100.82.112+bdcom-0ubuntu4 caused a kernel crash
(see bug 1089114). I have been running Raring through all kernels
released without any problems until 3.7.0-6 *and* bcmwl 6.20.155.1.
