Kernel 'bisection'

[Chris]

Who can give me some pointers on doing a kernel bisection on either
3.13.0-35 or -36 kernels? Ever since one of those two were installed,
I'm on -45 now, my system will lockup (black screen, cursor moves, but
CTRL-ALT-F1 will not take me to a terminal log-in. This is the error I
see - Feb 13 19:05:22 localhost kernel: [807775.808019]
[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... render
ring idle. I've reported this last year on Launchpad as bug -
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1402331 I've jumped
through all the hoops that have been suggested there except doing a
kernel bisection which seems to have me confused. I'm really getting a
bit tired of these continued 'lockups'.
