Like Emmanuel said, first a fix has to go upstream, then it can go to the 4.4 stable kernel, and then it'll probably end up in the Ubuntu kernel. Can you post a metadump of the xfs filesystem somewhere for further analysis? I'm pretty sure it's the same problem reported by David Shaw on this list a couple of weeks ago. Since you can't run one-off test kernels, send us a metadump for recreation in a lab is the only other way to figure out if the fix works. (And yes, I /do/ have a lightly tested fix which I'm about to send out.) --D > -- > To unsubscribe from this list: send the line "unsubscribe linux-xfs" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-xfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
