Comment 8 for bug 1074349

Olivier FEBWIN, thank you for testing the mainline kernel. The next step would be to find the last known bad mainline kernel version, followed consecutively in version by the first good one (e.g. reverse mainline kernel version bisect). For more on bisecting please see https://wiki.ubuntu.com/Kernel/KernelBisection . Consulting http://kernel.ubuntu.com/~kernel-ppa/mainline/ we have:
v3.6.3-quantal/
v3.6.4-raring/
v3.6.5-raring/
v3.6.6-raring/
v3.7-rc1-quantal/
v3.7-rc1-raring/
v3.7-rc2-quantal/

Hence, could you please test http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6.6-raring/ ?

Thank you for your understanding.
