Its taking too long. I just suggested restricting concurrency but, that can't be right. The issue is IOVA - concurrency merely makes the bug more _likely_ to show up so in fact that won't work. -rc1 hits soon, if sub-nodes isn't ready to go by that point there is no choice but to implement BROKEN or minItems, 100% up to qcom to decide which. --- bod
