The sysrq+w should happen when the hang is happening. This dumps hanged task info to kernel messages (dmesg) but can sometimes be bigger than the default buffer, but all of it will be in journalctl -k (as well as all kernel messages since boot which can sometimes be useful). -- Chris Murphy -- 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
