If so, they are not in the sources. I would like the patches, please.
Also, the interface between the IPMI serial driver and the serial interface has changed a lot between the 2.6.21 and 2.6.22 versions. > Do ipmi_msghandler use DDI exported by ipmi_serial ?

In the interface from userland to the driver, you supply the NetFN and the cmd. The IANA is part of the data for OEM messages. The driver takes care of the sequence numbers. You are going to have to read Documentation/IPMI.txt and some IPMI stuff to learn how these things work. -corey ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
