    I've seen this if the array or partition table is corrupted. The check is
    at the front of dscheck() in src/sys/kern/subr_diskslice.c. You might
    make sure your raid array is functioning normally and the fdisk table
    hasn't been spammed.

    It shouldn't happen -- you might go exploring with fdisk(8).
