Dell Latitude E5540 http://www.ubuntu.com/certification/hardware/201307-13942/ on 12.04.4
steps to reproduce this bug:
1. get the propietary driver which jockey tells you [1]
2. sudo dkms install -m bcmwl -v 6.20.155.1+bdcom [2]
3. sudo modprobe wl
4. lsmod | grep wl
expected result:
wl.ko is working and there is wireless
actual result:
wl.ko was inserted but there is kernel panic.
wireless didn't work.
[1]
the steps to get the propietary driver in my case is
1. after installation 12.04.4, jockey will tell you there is propietary driver for the wireless.
2. click jockey to download and install the driver.
3. jockey will be on the stage of the "downloading" dialogue window
4. go to check the /var/log/jockey.log, I found
* jockey has downloaded the driver and built the wl.ko
* "Segmentation fault" after the dkms was installed
[2]
build and install the dkms, it looks ok for this step
