Bisect instructions:

install git

$ git clone
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
$ cd linux-2.6
$ cp /path/to/.config .config

# if you don't have a specialized .config already:
$ make localmodconfig

$ git bisect start v2.6.39 v2.3.39-rc1

$ make -j20 && sudo make modules_install install

[reboot to new kernel]
[test]

If it works okay:

$ git bisect good

otherwise:

$ git bisect bad

if git says there is work to do:

[goto 'make' step]

otherwise:

post the message that says: xxxxxxxxxxxx is first bad commit

Note: please test v2.6.39 and v2.6.39-rc1 first, to be sure they're bad
and good, respectively. You can do that using

$ git checkout v2.6.39
$ make -j20 && sudo make modules_install install
[reboot and test]
$ git checkout v2.6.39-rc1
$ make -j20 && sudo make modules_install install
[reboot and test]

Note2: if the problem also occurs when qemu-kvm is running in a guest,
you can run all of the tests in a guest, which should be a more
pleasant experience.
