Hello
Found a bug in FreeBSD 10.2.
An UFS disk slice created under sparc64 cannot be mounted under amd64.
And reverse: UFS disk slice created under amd64 cannot be mounted
under sparc64. This also happens with hard disks on both MBR and VTOC8
partition schemes, on both UFS and ZFS filesystems.

As we can see, both kernels are the generic.
This is how you can simply reproduce the bug:
_____________________________________
amd64:
-> create 400MB disk image with dd, attach to md and format with newfs
-> mount, copy some stuff(/bin), unmount, detach from md;
-> md5+sh256 check of the image to see if they match when sent to the
other side;
-> send it with ftp to the sparc64 machine
