Why is this guy filling the place with Linux dmesg messages?

I think it has, yes.
As you say, Joe is building the kernels and passing them to me for
testing so hopefully we will home in on the offending code over the
next few days.

I think Joe is helping you now, but for completness ...

The builds you are referring to are the mainline builds.  Strictly
there are no tags for those, you would reconstruct those by cloning
the linux-stable tree and checking out the commit listed in COMMIT in
the same directory as the downloaded binaries.  After that applying the
patches -* in the same directory will recreate the tree the builder
used to make the binaries.

Hope that helps.

Hi Colin,

Thanks for opening the bug.  I'll perform the bisect for you.  I just
update the bug with a couple of kernels to test before starting the bisect.

Thanks,

Thanks Nicholas

I think those links refer mainly to getting as far as which released
ubuntu version exhibits the problem, I was intending (and have
achieved to some extent, as described in my other post) to build the
kernel and bisect it down to find the commit that introduced the
problem.  I was referring to
https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel for this.

Cheers

Colin

Hi Joe

Thanks for the offer. There was an existing bug
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/887793 but that
has become out of date I think so I have opened a new one
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1491467

I have determined that the last of the 3.19 kernels is ok but the
first version in the wily tree that will build using fakeroot
debian/rules binary-headers binary-generic, which is

commit 636cdd7b2930ca2cdaf90eedd04fdb9fc7a8d5ec

Hi Colin,

Nicholas is correct with the location of the mainline tree.  You could
also perform the bisect with the Wily tree, but it's usually more
straight forward to use the mainline tree.

One thing to note, 3.19.8 and 4.0-rc1 are not linear tags.  The kernel
forks when 3.19.1 is released as the first 3.19 stable version. 
Mainline then continues along with 4.0-rc1.  This means that you can
only bisect between v3.19 final and v4.0-rc1.  That is as long as you
are sure that 3.19 final does not have the bug and 4.0-rc1 does. 

Did you happen to open a Launchpad bug for this?  If so, can you send
the bug number?  I'd be more than happy to help you perform this
bisect.  I can perform the bisect and build test kernels for you to
test.  You would then just need to report back if the test kernel
exhibits the bug ore not.

Thanks,

Joe

Fwd: [Ubuntu-phone] Next generation of SDK

[Nicholas Skaggs]

Those of you who are into phone development, or just curious, the SDK 
team would love some feedback on the new Ubuntu SDK. Check out the info 
below.



 Forwarded Message 
Subject:[Ubuntu-phone] Next generation of SDK
Date:   Wed, 2 Sep 2015 10:13:32 +0300
From:   Zoltán Balogh 
To: ubuntu-phone 



Hi all,

I have just posted on the Developer blog ->

https://developer.ubuntu.com/en/blog/2015/09/01/next-generation-sdk/

I kindly invite anybody for testing this new kind of Ubuntu SDK.

No need to get scared :) the UI and the flow is the same as now... just
much faster to set up and brings the very same bits to LTS users as to
Wily riders.

For the brave it takes only that much ->

$ sudo add-apt-repository ppa:ubuntu-sdk-team/tools-development -y &&
sudo apt-get update
$ sudo apt-get install ubuntu-sdk-ide ubuntu-sdk-api-tools
ubuntu-sdk-api-15.04-armhf ubuntu-sdk-api-15.04-i386

After that you can have a hot beverage break :) depending on your
network as it downloads ~1GB data. But once it is done, you are good to
go :)

Note, this is not officially released yet! It is more like a tech preview.

Feedbacks, comments and ideas are welcome.

cheers,

bzoltan

Adding in the kernel team who might be able to help more. Colin, have 
you seen / read https://wiki.ubuntu.com/Kernel/KernelBisection?


If I had to guess, I'd be looking in the mainline tree: 
http://kernel.ubuntu.com/git/ubuntu/linux.git, and the conversion table 
http://people.canonical.com/~kernel/info/kernel-version-map.html. 
Really, that wiki should have all the information you need to do the 
bisection.


Thanks for making ubuntu better by tracking this down, and good luck!
