Hi Rene, I got time to work on this only now. I think you have changed
the pass code.

OpenBSD guys got inband driver to work on IBM e325. This looks like a
BMC firmware bug. Refer to 

Can you please try "no-probing" option. This will force the KCS driver
to use successive reg-spacing (=1byte) and I/O mapped access.

 # bmc-info --no-probing

Second thing I may try is to increase the value of
libfreeipmi/src/ipmi-kcs-api.c:IPMI_KCS_SLEEP_USECS to something
higher. Because MSI's BMC is slow in I/O.

We may also need SDR firmware fixes. I will tell you what you need to
report to IBM once we get the basic stuff to work.
