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.
