We have a bingo! Reverting "qgroup: Fix qgroup accounting when creating snapshot" from last Wednesday immediately fixes the problem. Was quite easy to find - the triggered WARN_ON was the second one that complained about a mismatch between roots. The only patch that even remotely did something in that area was said qgroup fix. Looks like something is missing there. Suggestions welcome. :) Holger -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
