Comment (by robe):

 Looks like the commit broke interruptability on  winnie, tried triggering
 a number of times and fails in same spot.
 The 3.5 branch of hers was green before this. 5 minutes is hard to ignore,
 but since the other interrupts are passing perhaps its only the GEOS one
 at issue.

 On winnie I see this, but interrupt and interrupt_relate are okay

 Dronie did fail once, but I think this is a random interrupt failure

 On dronie:
