Hey Jason,

I just got 2 reports with problems on ubuntu with 4.15 kernel.

When their are loading in the kernel module it wil crash on: 

wireguard: Unknown symbol poly1305_blocks_avx (err 0)
wireguard: Unknown symbol poly1305_emit_avx (err 0)
wireguard: Unknown symbol poly1305_blocks_avx512 (err 0)
wireguard: Unknown symbol chacha20_avx512vl (err 0)
wireguard: Unknown symbol chacha20_avx2 (err 0)

I just install a fresh ubuntu xenial with kernel 4.15 and it works just
fine.

Any clue what problem kan be?
