All the jobs that you've listed hang in the very same test 
(qtest-i386/boot-serial-test), so I assume it's rather a test that now hangs 
occasionally, and not a generic slowness (otherwise the jobs would fail 
sometimes earlier, sometimes later).

Thus we likely have a regression in the code that only shows up occasionally 
in these builds... Can you mark a point in time when these issues first 
happened?
