I believe I have seen a similar failure on i386 when the disklabel and the
FFS superblock disagreed about the size of blocks and fragments, and/or
when the kernel grew big enough to require a 2nd or 3rd level of inode
indirection.  Are the kernels both on a FFS filesystem?  How big are they?
What does disklabel(8) say about the disk where the kernels reside?
