Bug 1066524 Bisection Inquiry

[Christopher M. Penalver]

Dear Ubuntu Kernel Team:

I am contacting you to seek help in performing a commit bisect of bug
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1066524 .
Following https://wiki.ubuntu.com/KernelTeam/GitKernelBuild when I
execute the following terminal command:
cd ~/Desktop && git clone
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git && cd
linux && git bisect start && git bisect good v2.6.34-rc1 && git bisect
bad v2.6.34 && git checkout fd218cf9557b9bf7061365a8fe7020a56d3f767c
&& cp /boot/config-`uname -r` .config && yes '' | make oldconfig &&
make clean && make -j `getconf _NPROCESSORS_ONLN` deb-pkg
LOCALVERSION=-custom

an error notes:
include/linux/pagemap.h:415:16: warning: variable ‘c’ set but not used
[-Wunused-but-set-variable]
  LD [M]  fs/xfs/xfs.o
  LD      fs/built-in.o
make[1]: *** [deb-pkg] Error 2
make: *** [deb-pkg] Error 2

Unfortunately, because I'm a newb, I don't understand what the error
means, what caused it, or how to figure out how to fix it. What would
I be doing wrong?

Thank you for your time and consideration in this matter, and I look
forward to your response.
