These are fine, they are kernel accesses that are being fixed up.
Unfortunately some of the networking paths generate lots of unaligned
kernel traps, so we will probably have to go back to having a default of
not warning on them at all. In any event, this behaviour is tunable.
Just open up arch/sh/kernel/traps_32.c and change se_kernmode_warn to 0.
