Hi,

I'm seeing more recent tests in the same stream that work, but e.g.
linus is failing.

It's failing across all the tests, which suggests a systemic problem.

Some ideas:

   1) bad kernel commit causing the problem
   2) It's not actually running the tests on an ARM machine :-)
   3) Faulty hardware

1 looks unlikely because we have the same revision of the kernel failing and passing
in different runs.

3 looks unlikely because sometimes the same board will fail and sometimes it will
pass (I haven't looked carefully enough to find an instance where it fails and then
passes, so it could be that a number of boards are failing.)

The toolchain looks unlikely to be implicated unless we are varying the toolchain
used to build the kernel, but even then we currently have arm-soc passing and linus
failing, and presumably they would be built with the same toolchain.

Therefore I don't have a clear idea of where the problem lies currently.

Thanks,

James
