Host SMBus controller not enabled! on Redhat 7.6
Error : Host SMBus controller not enabled! In order to fix it, I modified and add one line to dccp-blacklist.conf file . Redhat depricated the module: for security reasons, automatic loading of the Datagram Congestion Control Protocol (DCCP) kernel modules through socket layer is now disabled by default. blacklist i2c-piix4 ls -ltr /etc/modprobe.d/blacklist.conf cd /etc/modprobe.d/ ls -ltr cp dccp-blacklist.conf dccp-blacklist.conf.sid ls -ltr vi dccp-blacklist.conf Add blacklist i2c-piix4 then save it. Followed by reboot.
