Yes, you can. However, you better upgrade directly from 10.4 to 11.2 when using source upgrade path
to save the time and troubles.

signal 12 is SIGSYS meaning that your binaries use syscalls that kernel does not have,
so you either still run old 10.4 kernel with new binaries or you run new custom 11.0 kernel
built without options COMPAT_FREEBSD10 and old binaries.

There are many possible cases for this. For example, if you have degraded gmirror then
you might installed new kernel and binaries to one part of the mirror only (due to its degraded state)
but loader boots old kernel using another part of the mirror because it known nothing about gmirror
and uses BIOS service to read plain disk (make it boot from another part forcebly then).

Or some another glitch, verify installed data carefully.

If you run new custom 11.0 kernel built without options COMPAT_FREEBSD10 and old binaries,
then use loader to unload new kernel and load kernel.old before booting.
