Comment 17 for bug 1215513

Oibaf, dac922: thank you for your comments. Since bug #1217189 also refers to "possibly causing complete machine lockup" (see title) I decided to set it as a dup.

Anyway, I was actually convinced the fix pointed in comment #13 was already in Raring but looks like I was wrong -- its in Quantal kernel only. I'll make sure it hits the 3.8.y stable kernel which will then be picked into Raring.
