Some Intel Tiger Lake-UP3/UP4 CPU models (TGL, family 6, model 140, stepping 1)
|
|
|
|
|
had reports of system hangs when a microcode update, that was included
|
|
|
|
|
since microcode-20201110 update, was applied[1]. In order to address this,
|
|
|
|
|
microcode update had been disabled by default on these systems. The revision
|
|
|
|
|
0x88 seems to have fixed the aforementioned issue, hence it is enabled
|
|
|
|
|
by default (but can be disabled explicitly; see below).

The information regarding disabling microcode update is provided below.
|
|
|
|
|
|
|
|
|
|
To disable 06-8c-01 microcode updates for a specific kernel
|
|
|
|
|
version, please create a file "disallow-intel-06-8c-01" inside
|
|
|
|
|
/lib/firmware/<kernel_version> directory, run
|
|
|
|
|
"/usr/libexec/microcode_ctl/update_ucode" to remove it from the firmware
|
|
|
|
|
directory where microcode is available for late microcode update, and run
|
|
|
|
|
"dracut -f --kver <kernel_version>", so initramfs for this kernel version
|
|
|
|
|
is regenerated, for example:
|
|
|
|
|
|
|
|
|
|
touch /lib/firmware/3.10.0-862.9.1/disallow-intel-06-8c-01
|
|
|
|
|
/usr/libexec/microcode_ctl/update_ucode
|
|
|
|
|
dracut -f --kver 3.10.0-862.9.1
|
|
|
|
|
|
|
|
|
|
To avoid addition of this microcode for all kernels, please create file
|
|
|
|
|
"/etc/microcode_ctl/ucode_with_caveats/disallow-intel-06-8c-01", run
|
|
|
|
|
"/usr/libexec/microcode_ctl/update_ucode" for late microcode updates,
|
|
|
|
|
and "dracut -f --regenerate-all" for early microcode updates:
|
|
|
|
|
|
|
|
|
|
mkdir -p /etc/microcode_ctl/ucode_with_caveats
|
|
|
|
|
touch /etc/microcode_ctl/ucode_with_caveats/disallow-intel-06-8c-01
|
|
|
|
|
/usr/libexec/microcode_ctl/update_ucode
|
|
|
|
|
dracut -f --regenerate-all
|
|
|
|
|
|
|
|
|
|
Please refer to /usr/share/doc/microcode_ctl/README.caveats for additional
|
|
|
|
|
information.
