Comment 37 for bug 1547838

I have narrowed it further to these builds.

3.9.0-7.15 - good
3.10.0-0.6 - bad

I've managed to fetch the saucy repo. git says there's around 14,000 commits between these two tags?!

I'm going to first verify that when I build both of these tags I get the same behaviour as I do with the binary builds. Then I'll start the git bisect properly.

Unfortunately, as slow as my internet is, downloading kernels is quite a bit faster than building them appears to be :(
