Comment 25 for bug 1216422

Launhcy, now that we know that this regression occurred between Ubuntu kernel versions 3.1.0-2.3 and 3.2.0-1.1 the next is to commit bisect between them to identify the commit that caused this regression following https://wiki.ubuntu.com/Kernel/KernelBisection#Commit_bisecting_Ubuntu_kernel_versions .
