I was able to reproduce the issue on a stock Jessie install on a Vostro
1320 (featuring a BCM 3412). Kernel versions after 3.17 (including
3.18.12, 3.19.0, 3.19.6 and 4.0.1, at least these are the ones I checked
myself) seem to have an issue which causes the kernel to lock up.
BCM4331 causes an immediate freeze, whereas BCM 1312 (and as ralphb
pointed out above BCM 4360) only show these symptoms after actual
payload transmission. This goes for bcmwl versions 6.30.223.248 and
6.20.155.1.

I heard at a LUG meeting that Fedora 21/22 apparently contain special
patches which at least support an MBP mid-2013. I will verify this and
report results back asap.

Given that the kernel maintainer closed this issue (a move which I can
only follow partly as wl works fine on pre-3.18 kernels) and BCM chips
are pretty popular among laptop manufacturers: Could somebody upstream
please assign this and bump it up so that we can get a resolution
quickly?

More than happy to provide additional information in the meantime - just
let me know what is needed (unfortunately, the wl driver doesn't seem to
support debugging information generation beyond the usual).
