  This doesn't look very good.  From the 2.1 install kernel off of
ftp.netbsd.org:

amiga$ gdb /tmp/netbsd-INSTALL
...
(gdb) x/i 0x3b3e8
0x3b3e8 <in6_domifattach+14>:   bchg %d6,%d0
(gdb) x/8i in6_domifattach
0x3b3da <in6_domifattach>:      linkw %fp,#0
0x3b3de <in6_domifattach+4>:    moveml %a2-%a4,%sp@-
0x3b3e2 <in6_domifattach+8>:    clrl %sp@-
0x3b3e4 <in6_domifattach+10>:   pea 0x200d40 <M_IFADDR>
0x3b3ea <in6_domifattach+16>:   pea 0xc <kernel_text+12>
0x3b3ee <in6_domifattach+20>:   lea 0xd1970 <malloc>,%a3
0x3b3f4 <in6_domifattach+26>:   jsr %a3@
0x3b3f6 <in6_domifattach+28>:   moveal %a0,%a2
(gdb) quit


  The instruction from your output looks like it could be off by 2 bytes:

(gdb) x/i in6_domifattach
0x3b3da <in6_domifattach>:      linkw %fp,#0
(gdb) x/i in6_domifattach+2
0x3b3dc <in6_domifattach+2>:    orib #-25,%d0
