bhyve remote kgdb does not support kernel modules...

So, I got remote kgdb working w/ bhyve, but kernel modules aren't

I'm getting:
(kgdb) bt
#0  kdb_enter (why=0xffffffff8102ee88 "panic", msg=<value optimized out>)
    at ../../../kern/subr_kdb.c:444
#1  0xffffffff8094aa79 in vpanic (fmt=<value optimized out>,
    ap=<value optimized out>) at ../../../kern/kern_shutdown.c:739
#2  0xffffffff8094a8c9 in kassert_panic (fmt=<value optimized out>)
    at ../../../kern/kern_shutdown.c:634
#3  0xffffffff8093583c in __mtx_lock_flags (c=0xfffff80002919720, opts=0,
    file=0xffffffff81c3f0fa "/usr/home/jmg/freebsd.p4/opencrypto/sys/modules/aesni/../../crypto/aesni/aesni.c", line=442) at ../../../kern/kern_mutex.c:217
#4  0xffffffff81c3e3a7 in ?? ()
#5  0xfffff80002a474a0 in ?? ()
#6  0xfffff80002919720 in ?? ()

Where those should be in the aesni.ko module...  If I run kgdb on a
local machine, it properly finds the kernel modules... Any hits on
how to fix this?
