Hi. Sorry, I just don't have the time to locate the commit that fixes
the issue. My machine is old and slow, so even building the kernel once

Ideally we could get Canon
Hi. I would prefer a backport to 14.04 if that's not to much trouble,

Hi Brad,
Which kernel do you want me to be booted into when I run apport-collect?
The last version before the break (3.13.0-68); the first version available
after the break (3.13.0-70); or the current version (3.13.0-74)? Or
doesn't it matter at this point?
Thanks, Lucas.
