I seem to have mislaid my microcode somewhere, in the latest stable gentoo kernel:
# grep -i MICROCODE .config
#
As a result I get this during boot:
# /etc/init.d/microcode_ctl start
* Updating microcode ...
microcode_ctl: cannot open /dev/cpu/microcode for writing errno=2 (No such
file or directory)
* Failed to update microcode via '/dev/cpu/microcode'
[ !! ]
* ERROR: microcode_ctl failed to start
The previous kernel contained this:
# grep -i MICROCODE /boot/config-4.1.15-r1-gentoo
CONFIG_MICROCODE=y
CONFIG_MICROCODE_INTEL=y
# CONFIG_MICROCODE_AMD is not set
CONFIG_MICROCODE_OLD_INTERFACE=y
Is there something else I ought to switch on first?
