 The problem still exists on 8.2-RC1.

 FreeBSD beastie.home.lan 8.2-RC1 FreeBSD 8.2-RC1 #0: Thu Dec 23 15:32:35 UTC 2010     root@almeida.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  i386

 Steps to reproduce the issue:

 # swapoff -a
 # geli load
 # geli onetime -a HMAC/SHA1 -e AES-CBC -s 4096 -d /dev/ad0s1b
 GEOM_ELI: Device ad0s1b.eli created.
 GEOM_ELI: Encryption: AES-CBC 128
 GEOM_ELI:  Integrity: HMAC/SHA1
 GEOM_ELI:     Crypto: software
 GEOM_ELI: ad0s1b.eli: 4096 bytes corrupted at offset 954429440.
 GEOM_ELI: ad0s1b.eli: 8192 bytes corrupted at offset 65536.
 GEOM_ELI: ad0s1b.eli: 8192 bytes corrupted at offset 8192.
 GEOM_ELI: ad0s1b.eli: 8192 bytes corrupted at offset 0.
 GEOM_ELI: ad0s1b.eli: 8192 bytes corrupted at offset 262144.
 GEOM_ELI: ad0s1b.eli: 8192 bytes corrupted at offset 65536.
 GEOM_ELI: ad0s1b.eli: 8192 bytes corrupted at offset 8192.
 GEOM_ELI: ad0s1b.eli: 8192 bytes corrupted at offset 0.
 GEOM_ELI: ad0s1b.eli: 8192 bytes corrupted at offset 262144.
 GEOM_ELI: ad0s1b.eli: 4096 bytes corrupted at offset 32768.
 GEOM_ELI: ad0s1b.eli: 4096 bytes corrupted at offset 0.
 GEOM_ELI: ad0s1b.eli: 4096 bytes corrupted at offset 8192.
 GEOM_ELI: ad0s1b.eli: 4096 bytes corrupted at offset 65536.
 GEOM_ELI: ad0s1b.eli: 4096 bytes corrupted at offset 0.

 This happens with any data integrity verification algorithm.

 Also, newfs'ing a HMAC/* geli partition is not possible.
