I had another btrfs crash with identical symptoms. This time I managed to reproduce the crash and identify the root cause. It turns out that the Apple boot firmware is buggy and leaves wifi DMA turned on, which randomly corrupts memory after Linux is running. https://bugzilla.kernel.org/show_bug.cgi?id=111781
So btrfs is not to blame after all. -- 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
