Version-Release number of selected component (if applicable): microcode_ctl-1.11-1.21 How reproducible: Didn't try Steps to Reproduce: 1. Install FC4 on x86 machine 2. 3. Actual Results: microcode_ctl is not installed Expected Results: microcode_ctl must be installed Additional info: Perhaps this is actually an Anaconda bug?
Even so, microcode_ctl complains about non-existent /dev/cpu/microcode To fix that, I had to create the executable file named /etc/sysconfig/modules/microcode.modules with the following content: #!/bin/sh /sbin/modprobe microcode After that microcode_ctl works fine when booting up.
The first bug would be the comps.xml package that defines whether things get installed or not. The second bug should be fixed in the latest errata.
FC6 will have microcode_ctl as a default of the Base group that can be opted out of.
