Check your disk label. I got burned a few months back on a fairly old install where I created swap first, then root. This causes the swap partition to start at sector 0, with root straight after. For some reason, sysinstall or the kernel decided to += 64k on the start address of the swap partition (to avoid swap clobbering the fdisk, bootblocks, etc at the start of the disk), but neglected to remove 64k from the size. So, when I finally crashed the box with dumps enabled, it took out the first 64k of my root filesystem. I never found the code that made this change. Either it is well hidden, or got removed a while back. This machine was installed from a 4.0-SNAP from some time before march 1999.
