It looked to me like that's the same kernel that's in artful release, so
instead I tried with the kernel in artful-proposed (4.13.0-17.20) and
managed to reproduce the bug on 1/6 instances after a few reboot cycles.
So I think my method is okay to check candidate kernels. Feel free to
throw some more at me if you want to bisect.

(I think IS took some of the slower machines out of rotation so the
problem might become slightly harder to reproduce - definitely is still
happening though.)
