Padlock with VIA Nano still crashing

Padlock with VIA Nano still crashing

[Nico Erfurth]

Hi,

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.

Regards,
Nico

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.
