I'm pretty sure you have CONFIG_DEBUG_BLOCK_EXT_DEVT enabled. This option must never be enabled, as it causes block devices to be randomly renumered. Together with the ramdisk driver overloading the BLKFLSBUF ioctl to discard all data it guarantees you to get data loss like yours. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
