--- Comment #25 from Lev A. Serebryakov <lev@FreeBSD.org> ---
(In reply to Conrad Meyer from comment #23)

Now I have:

igb + AESNI + bpf =E2=80=94 one crash on older revision, no crashes for sev=
eral hours
of testing on newer revisions. It is very first stack trace, and I can not
reproduce it anymore (with or without bpf). Looks like, we could skip this,=
 as
it is not reproducible.

em + !AESNI =E2=80=94 crash with or without bpf. All other stack traces (wi=
th
IBVARIANTS and without them) are for this configuration. Looks like, bpf is=
 not
evolved at all.

Unfortunately, I can not swap NICs or CPUs, as it is embedded-like hardware
with everything soldered on board.

I'll try igb + !AESNI tonight by unloading aesni.ko in first place.

I'll send you URL for kernels + dumps via e-mail, as I'm not sure it doesn't
contain sensitive data (it should not, but though).

11-STABLE which serves as "other end" of this test setup is r338960.
