Package: broadcom-sta-dkms Version: 5.100.82.112-8 Severity: normal when inserting the wl module as built using dkms by broadcom-sta-dkms in a 3.7 kernel (allegedly exactly since 3.6.1), it a kernel BUG message appears on the screen, the wifi still doesn't work, and all kinds of things go bad as usual after kernel bug messages. see the attached dmesg output for the exact message.
the problem is known and well described in redhat[1], which links to a discussion at rpmfusion[2] that contains a patch[3]. i applied that patch on the dkms sources, and the resulting built kernel module works fine for me.
