--- Comment #4 from Alex Deucher alexdeucher@gmail.com --- There are tons of git bisect howtos. You will need to checkout the stable kernel git tree, build and install it. Here are the basics:
# 1. clone the git tree git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git cd linux-stable # 2. copy the config from your currently running kernel cp /boot/config-4.0.4-<whatever> .config # 3. start the bisect git bisect start git bisect good v4.0.4 git bisect bad v4.0.5 # 4. build and install the kernel make make modules_install make install # 5. reboot and test of the kernel is working # 6a. if so mark the commit as good git bisect good # 6b. else mark it as bad git bisect bad # 7. repeat steps 4-6 until git has identified the problematic commit
