Cannot load ipmi_si properly with Kernel 3.10.x on MIC-5322

Purpose:

Customer reports when they upgrade OS to Kernel 3.10.x (previous 2.6.32.x.) and faced an issue where the IPMI fail to load. 

Customer tried to restart “ipmi service”, but the module still fails to load and see the following messages in dmesg: 

ipmi_si: Unable to find any System Interface(s)

Probably the new kernel version that doesn’t recognize the BMC chip on MIC-5322, but same environment is working on MIC-5332 as expected.

Target Audience:

All users who are using Linux OS with specific kernel based on Advantech MIC-5322.

Solution:

To solving this , user may reload the ipmi_si driver with proper parameters. That's because BIOS doesn't report IPMI SI device correctly, thus a driver parameter is required. plz check attached log for more detail.

modprobe ipmi_devintf
modprobe ipmi_msghandler
modprobe ipmi_si type=kcs ports=0xca2 regspacings=1
