Raw Blame History

Some Dell systems that use some models of Intel CPUs are susceptible to hangs
and system instability during or after microcode update to revision 0xc6/0xca
(included as part of microcode-20191113/microcode-20191115 update that addressed
CVE-2019-0117, CVE-2019-0123, CVE-2019-11135, and CVE-2019-11139)
and/or revision 0xd6 (included as part of microcode-20200609 update
that addressed CVE-2020-0543, CVE-2020-0548, and CVE-2020-0549)
[1][2][3][4][5][6]. In order to address this, microcode update to the newer
revision has been disabled by default on these systems, and the previously
published microcode revisions 0xae/0xb4/0xb8 are used by default
for the OS-driven microcode update.

The information regarding disabling microcode update is provided below.
To disable usage of the newer microcode revision for a specific kernel
version, please create a file "disallow-intel-06-8e-9e-0x-dell" inside
/lib/firmware/<kernel_version> directory, run
"/usr/libexec/microcode_ctl/update_ucode" to update firmware directory
used for late microcode updates, 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-06-8e-9e-0x-dell
/usr/libexec/microcode_ctl/update_ucode
dracut -f --kver 3.10.0-862.9.1
To disable usage of the newer microcode revision for all kernels, please create
file "/etc/microcode_ctl/ucode_with_caveats/disallow-intel-06-8e-9e-0x-dell",
run "/usr/libexec/microcode_ctl/update_ucode" to update firmware directories
used for late microcode updates, and run "dracut -f --regenerate-all"
so initramfs images get regenerated, for example:
mkdir -p /etc/microcode_ctl/ucode_with_caveats
touch /etc/microcode_ctl/ucode_with_caveats/disallow-intel-06-8e-9e-dell
/usr/libexec/microcode_ctl/update_ucode
dracut -f --regenerate-all
Please refer to /usr/share/doc/microcode_ctl/README.caveats for additional
information.
