This bug was accidentally moved from POST to MODIFIED via an error in automation, please see mmccune with any questions

Comment 3 Niels de Vos 2016-08-07 15:50:47 UTC

I think I found a potential fix for this. Will re-use the Change-Id if I have a fix, or at least verify that your patch prevents spurious failures.

Thanks!
