Didn't trigger during a week of other work, yet a kernel compile triggers this reliably. Filesystem appears consistent (btrfs check, scrub). Mount options: noatime,compress=lzo,ssd,space_cache. -- An imaginary friend squared is a real enemy. -- 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
