As part of ZFS Crypto, I started getting a series of panics when I did not have AESNI loaded. Adding locking fixed it, and I concluded that the Reinit function altered the AES key schedule. This locking is not as fine-grained as it could be (AESNI uses per-cpu locking), but it's minimally invasive.
