Title:
@jderose - Thanks for catching the error with my commit ID, yes that is
the commit I meant to refer to.
Also, I seem to be getting intermittent behavior still when connected to
a 5GHz wireless AC network. I haven't tested others, but even with the
bluetooth off I am getting random disconnects. I t
I am perplexed to report that, although I am able to reproduce the error
on 4.0, I am not able to reproduce it on 4.1. Furthermore, directly
after writing the above comment, I updated my Arch Linux install, and
now the wifi fails in a completely different way than described above,
so I really don't
Understood. It just seemed that if there was a bug in the upstream kernel
and (for instance) the Arch kernel team had found it, it would similarly be
reported back upstream, not to mention that Arch seems quite against making
upstream modifications.
In any event, I am in the process of reverse com
I reverse bisected the upstream kernel, and determined that the fix is
in commit 16c426f. I also believe that this is (upstream) already set to
be merged into the 3.19 kernel (please let me know if that's not the
case).
Specifically, there is only one small change in this commit, which
adjusts the

The above logs are from apport on Ubuntu Vivid running the 3.19 kernel
(fully updated at time of posting).
I also updated to newest version of kernel (4.0.0-04rc7-generic) as
you requested, and the problem persists as before. Do you want more
apport logs from the new kernel as well?

The wireless card also works in Arch Linux using this kernel:

I cloned the git repo for the Ubuntu kernel and I built a number of test
kernels. It seems like the problem starts in 3.18.0-1.1, here are the
kernels tested:
Good
3.16.0-23.31
3.16.0-24.32
3.16.0-25.33
3.16.0-28.38 *

3.18.0-1.1
3.18.0-7.8

3.19.0-13.13

The asterisk mentioned above (for kernel 3.16.0-28.38) should be
disregarded - the behavior was present for a few tests, but I have
repeatedly tested it at this point and I think it was just typical wifi
wonkyness rather than the indication of a problem. Therefore,
3.16.0-28.38 should be regarded a
I figured out how to do a kernel bisection manually, and isolated the
first bad commit to this one:

I thought that is exactly what git bisect does.
In any event, I manually created a new branch and compiled the kernel

works, commit ab1304b986468e3ef698ec4e1cb1a3d4ba080811 does not.
Furthermore, checking out Ubuntu 3.19.0-13.13 and reverting commit
ab1304b986468e3ef698ec4e1cb1a3d4ba080811 (which requires making a minor
merge conflict adjustment)
I think perhaps I'm using the wrong vocabulary, which is the cause of
confusion.
When I did the git bisect I tested each bisection point manually, so I
must have actually tested that commit at some point in the past

I understand what you're saying, however I'm confused as to why this
would work appropriately on other distributions with the newer (version
12) firmware. In particular, it works on Arch linux (mentioned above).
