このページを参考に kernel-firmwareのバージョンを変えた
diff -u /etc/yum/pluginconf.d/versionlock.list_org /etc/yum/pluginconf.d/versionlock.list --- /etc/yum/pluginconf.d/versionlock.list_org 2017-01-22 14:56:45.445033498 +0000 +++ /etc/yum/pluginconf.d/versionlock.list 2017-01-22 14:58:58.980396046 +0000 @@ -1,6 +1,6 @@ # Added locks on Thu Jan 16 20:14:15 2014 0:kernel-headers-2.6.32-431.3.1.el6.* -0:kernel-firmware-2.6.32-431.3.1.el6.* +0:kernel-firmware-2.6.32-642.13.1.el6.* 0:kernel-2.6.32-431.3.1.el6.* 0:kernel-devel-2.6.32-431.3.1.el6.*
そんでうまく行った
