I've tried to setup a fileserver with a Via Nano board (Jetway
NF77-N1G6) to use it's Padlock encryption engine. All works fine with
the software encryption, but when I try to use the Padlock driver I get
sporadic crashes while reading and writing on my encrypted device.
I can't provide the crashdump right now, because the machine itself is
not useable after the crash anymore. Whatever I try to do after the
kernel panic just results in another panic.
But I've compared the message with the sourcecode and it seems to point
to the "repz xcrypt-ecb" command used by aes_encrypt.
I've tried the latest cryptodev-2.6 and linux-2.6 (2.6.31-rc4) same
problem with both versions. (Which include fixes for the Via Nano)
Does anybody have an idea how I could get the crashdump so I can send it
to the list? If there is no other way I'll write it down next time.

If you have a serial port you could dump it there (console=ttyS0 in the
kernel command line).
Could you please provide /proc/cpuinfo? What parameters have you used to
create to setup your crypt partition (key size, cipher mode)?
I've tested crypto dev recently with ipsec and that seemed to work.
