Can somebody please offer some off list support to guide me through
'testing using the upstream kernel'?
I found a bug re a particular webcam, which is being diagnosed, and I
have been asked if I can test using the upstream kernel. There are
some guidance notes, but I need help to get my head round it.
I am willing to try, but not having done anything similar I want to
avoid wasting lots of time or getting an invalid result.
It's pretty easy actually.
http://kernel.ubuntu.com/~kernel-ppa/mainline/
That folder has a giant list of upstream kernels, both i386 and AMD64
builds.
This page describes how you do it:-
https://wiki.ubuntu.com/Kernel/MainlineBuilds
With this bit being the specific part you need:-
https://wiki.ubuntu.com/Kernel/MainlineBuilds#Installing_Mainline_Kernels
So what I'd do is:-
1) Figure out what version of kernel you're currently running with
"uname -a"
2) Look up the kernel on
http://kernel.ubuntu.com/~kernel-ppa/info/kernel-version-map.html and
see which mainline one it maps to
3) Go to http://kernel.ubuntu.com/~kernel-ppa/mainline/ and find the
mainline one you need
4) Download the files as per
https://wiki.ubuntu.com/Kernel/MainlineBuilds#Installing_Mainline_Kernels to
a folder
5) Open a terminal and navigate to the folder where you downloaded the
kernel deb files to.
6) Use "sudo dpkg -i linux*.deb" to install them
7) Reboot to the new kernel (use shift at boot time to force dpkg to
show a menu) and test your device.
Cheers,
Al.
