Some Intel Skylake CPU models (SKL-U/Y, family 6, model 78, stepping 3)
|
|
|
|
|
have reports of system hangs when revision 0xdc of microcode, that is included
|
|
|
|
|
since microcode-20200609 update to address CVE-2020-0543, CVE-2020-0548,
|
|
|
|
|
and CVE-2020-0549, is applied[1]. In order to address this, microcode update
|
|
|
|
|
to the newer revision has been disabled by default on these systems,
|
|
|
|
|
and the previously published microcode revision 0xd6 is used by default
|
|
|
|
|
for the OS-driven microcode update.

The information regarding enforcing microcode update is provided below.
|
|
|
|
|
|
|
|
|
|
To enforce usage of the latest 06-4e-03 microcode revision for a specific kernel
|
|
|
|
|
version, please create a file "force-intel-06-4e-03" inside
|
|
|
|
|
/lib/firmware/<kernel_version> directory, run
|
|
|
|
|
"/usr/libexec/microcode_ctl/update_ucode" to add it to firmware directory
|
|
|
|
|
where microcode will be available for late microcode update, and run
|
|
|
|
|
"dracut -f --kver <kernel_version>", so initramfs for this kernel version
|
|
|
|
|
is regenerated and the microcode can be loaded early, for example:
|
|
|
|
|
|
|
|
|
|
touch /lib/firmware/3.10.0-862.9.1/force-intel-06-4e-03
|
|
|
|
|
/usr/libexec/microcode_ctl/update_ucode
|
|
|
|
|
dracut -f --kver 3.10.0-862.9.1
|
|
|
|
|
|
|
|
|
|
After that, it is possible to perform a late microcode update by executing
|
|
|
|
|
"/usr/libexec/microcode_ctl/reload_microcode" or by writing value "1" to
|
|
|
|
|
"/sys/devices/system/cpu/microcode/reload" directly.
|
|
|
|
|
|
|
|
|
|
To enforce addition of this microcode for all kernels, please create file
|
|
|
|
|
"/etc/microcode_ctl/ucode_with_caveats/force-intel-06-4e-03", run
|
|
|
|
|
"/usr/libexec/microcode_ctl/update_ucode" for enabling late microcode updates,
|
|
|
|
|
and "dracut -f --regenerate-all" for enabling early microcode updates:
|
|
|
|
|
|
|
|
|
|
mkdir -p /etc/microcode_ctl/ucode_with_caveats
|
|
|
|
|
touch /etc/microcode_ctl/ucode_with_caveats/force-intel-06-4e-03
|
|
|
|
|
/usr/libexec/microcode_ctl/update_ucode
|
|
|
|
|
dracut -f --regenerate-all
|
|
|
|
|
|
|
|
|
|
Please refer to /usr/share/doc/microcode_ctl/README.caveats for additional
|
|
|
|
|
information.
