}

The Flame builds are only scheduled on a periodic basis, and self-serve won't allow me to retrigger ones inbetween (no job present with matching name, when trying the usual trick).

As such the regression range is quite large:
https://tbpl.mozilla.org/?tree=B2g-Inbound&jobname=flame&tochange=cff36dd6e717&fromchange=47876b558703

The lack of dep builds, the inability to easily retrigger, the unhelpfulness of the error message and the usual B2G obscurity due to multiple repos means the Flame builds do not meet https://wiki.mozilla.org/Sheriffing/Job_Visibility_Policy and so will be hidden until they do.

Bug 1016940 suspected to be the cause.

Device tree image cannot be produced because of the current kernel tree we use.

Comment 3

[Ryan VanderMeulen [:RyanVM]]

Flame builds are confirmed green again.
