[Ocf-linux-users] infinite wait in mv_cesa (Marvell Kirkwood) icw cryptotest

[Harro H. <hr...@gm...>]

Hello David,

I’m trying to get this driver working with a 3.6.33 kernel on my
OpenRD-Ultimate 88F6281 development board, but the cryptotest program
is waiting forever.

I am following this thread as well:
“[Ocf-linux-users] OCF driver for Marvell Kirkwood (88F6xxx) Processors”
http://sourceforge.net/mailarchive/forum.php?thread_name=8D145DCD0F55B543949BE94258003A200DF9AD4EA6%40exchange12.bdt-rw.de&forum_name=ocf-linux-users

Attached are my patches (fixes as described in the thread above) and
series file.

Do you have an idea why the system is hanging/waiting forever?

Thanks,

Harro
