Bug description:
[Impact]
Just loading the necessary modules is not enough to get a working IPMI system
interface (/dev/ipmi0) on Cavium ThunderX CRBs, and other ThunderX-based
Gigabyte servers. You have to do some magic:
echo ipmi_ssif 0x12 >/sys/bus/i2c/devices/i2c-4/new_device
or maybe:
echo ipmi_ssif 0x12 >/sys/bus/i2c/devices/i2c-5/new_device
Loading the modules should be enough.
[Test Case]
sudo modprobe ipmi_ssif
sudo modprobe ipmi_devintf
Do you have a working /dev/ipmi0?
sudo ipmitool lan print
[Regression Risk]
The driver being fixed is only used on ThunderX-based systems, and is
currently not usable w/o the above manual config.
