Now I 've tried to understand what happens by bisect. But when I followed the direction in wiki (https://wiki.ubuntu.com/Kernel/KernelBisection) I have some problems (see also http://ubuntu.5.x6.nabble.com/Update-https-wiki-ubuntu-com-Kernel-KernelBisection-Inquiry-td4997067.html). I have the same problems like described in http://forum.ubuntuusers.de/topic/kernel-fuer-git-bisect-kompilieren/#post-4465307.
I have done: git clone git://kernel.ubuntu.com/ubuntu/ubuntu-raring.git cd ubuntu-raring git checkout -b mybisect origin/master That's ok! But when I say: git bisect start Ubuntu-3.8.0-16.26 Ubuntu-3.8.0-15.25 I received: Bisecting: a merge base must be tested [405acc3402a3df8df967d1848947dc58f0059664] Linux 3.8.4 and the subdirectories debian and debian.master are deleted. Therefore I can't set an new version in debian.master/changelog and the the build of kernel to test with fakeroot debian/rules clean fakeroot debian/rules binary-headers binary-generic fails! I search in google how to build an own kernel and found: cp /boot/config-$(uname -r) .config make oldconfig fakeroot make deb-pkg This creates the files linux-image-3.8.4+_3.8.4+-1_amd64.deb linux-firmware-image_3.8.4+-1_amd64.deb linux-headers-3.8.4+_3.8.4+-1_amd64.deb linux-libc-dev_3.8.4+-1_amd64.deb I can install and test them. The result is good: git bisect good Bisecting: 280 revisions left to test after this (roughly 8 steps) [237e06fef3f2c5a461709904073f5ac587450839] UBUNTU: Temporarily disable module check on build All the following 8 steps are as result bad I got the last revision: Bisecting: 0 revisions left to test after this (roughly 0 steps) [74a6af256b4816bf95ca59323dc06b8001673a43] USB: EHCI: work around silicon bug in Intel's EHCI controllers But I don't know is this result significant? Perhaps the the tags are non-linear? So I tried to bisect the mainline kernels. I load the mainline kernels from http://kernel.ubuntu.com/~kernel-ppa/mainline/: v3.8.4-raring -> this is ok! v3.8.5-raring -> this implies the bug Now I done: git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git but the command "git bisect v3.8.4 good" fails with fatal: Needed a single revision Ungültige Referenz-Eingabe: v3.8.4 Now I don't know how continuing! I would like to help, but I need a little "how to" that works fine and give the correct results! -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1176126 Title: 045e:0721 Microsoft LifeCam NX-3000 not detected Status in “linux” package in Ubuntu: Confirmed Bug description: Since upgrate from quantal to raring I have the a problem with the webcam "Microsoft LifeCam NX-3000".
