As reported, it's flaky. Which means it might very well be only 
occurring under heavy load, or when specific other things are happening 
on the system. E.g. on i386, where only one debci worker runs per host, 
it seems to be much less flaky than on the other hosts where we run 
multiple (up to 18 on amd64) debci workers per host. You could try to 
spot patterns by matching timestamps of passing and failing tests to the 
historical performance [1].

It looks like each autopkgtest stanza has only one test, so yes, marking 
it flaky will resolve the problem (but also make the test close to 
worthless). (If on the contrary it's part of a whole test suite, you'd 
rather want to only mark the particular test as flaky or disable it, and 
not mark the autopkgtest stanza as flaky).
