Comment 4 for bug 2060748

For some reason, Launchpad will not let me upload the trace.dat file from trace-cmd.

As far as updating firmware for iwlwifi, do you have any guidance for how to upgrade firmware to -84 correctly. I am happy to try to see if it fixes the problem, but I am not familiar with the correct process for updating a firmware module out of standard apt tree and don't want to accidentally break something.
