Hi all,

I'm trying to use a Soekris Hifn 7955 based pci card to accelerate
dm-crypt device on vanilla 2.6.27-rc7 LK.

# cryptsetup luksFormat -c aes-cbc-plain -s 256 /dev/generic/test
completes successfully but the volume is unreadable.
Dmesg is

hifn795x 0000:03:04.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
hifn795x: assuming 66MHz clock speed, override with
hifn_pll_ref=ext<frequency>
hifn0: AES 128 ECB test has been successfully passed.
Driver for HIFN 795x crypto accelerator chip has been successfully
registered.
nommu_map_single: overflow 1fe047e00+512 of device mask ffffffff
nommu_map_single: overflow 1fe047e00+512 of device mask ffffffff
nommu_map_single: overflow 1fe047e00+512 of device mask ffffffff

The same works when I use software AES module. The hardware is a dual
opteron 252 with 8 GB RAM on a tyan S2882D mainboard. OS is Debian Lenny
i386. Kernel built from vanilla sources from kernel.org. The .config is
attached.
