--- Comment #2 from =C5=BDilvinas =C5=BDaltiena <zaltys@inbox.ru> ---
If nfsd on FreeBSD is explicitly limited to single thread, i.e. rc.conf wit=
h:

nfs_server_flags=3D"-t -n 1"

then transfers succeed with kr5i/krb5p and aesni module loaded even if linux
client does not use sync mount option. If thread count is set to > 1, origi=
nal
problem reappears. Some sort of thread safety / locking issue in sha part of
aesni module?
