Can you do a kernel bisection?

First, find the last good -rc kernel and the first bad -rc kernel from

$ sudo apt build-dep linux
$ git clone git://
$ cd linux
$ git bisect start
$ git bisect good $(the good version you found)
$ git bisect bad $(the bad version found)
$ make localmodconfig
$ make -j`nproc` deb-pkg
Install the newly built kernel, then reboot with it.
If the issue still happens,
$ git bisect bad
$ git bisect good
Repeat to "make -j`nproc` deb-pkg" until you find the commit that causes the regression.
