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

Purpose:

Customer reports they faced an issue that the IPMI fail to load, after they upgrade OS from kernel version 2.6.32.x. to 3.10.x.

Customer tried to restart “ipmi service”, but the module still fails to load and the following messages pops up 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. Please check attached log for more detail.

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