Canonical withdrew Microcode update for Intel Tiger Lake

Η Canonical απέσυρε την ενημέρωση Microcode της που κυκλοφόρησε στις 11 Νοεμβρίου για όλες τις υποστηριζόμενες εκδόσεις του to deal with a τος που προκαλεί αποτυχίες εκκίνησης σε ορισμένα συστήματα της Intel Tiger .

On November 10, Intel released a new firmware for Intel Microcode on Linux systems. After debugging, Canonical quickly fixed Intel Microcode packages on all supported versions of Ubuntu (Ubuntu 20.10, Ubuntu 20.04 LTS, Ubuntu 18.04 LTS, Ubuntu 16.04 LTS, and Ubuntu 14.04 ESM), and released new versions of kernel.

Unfortunately, the Intel Microcode update caused errors in some processors in the Intel Tiger Lake family, preventing the system from starting.

Therefore, Canonical again made the previous Intel Microcode update available only for the Tiger Lake family of processors.

The company informs users that they can use the parameter dis_ucode_ldr kernel in the boot menu to disable firmware loading for Intel Microcode in case of system recovery mode.

If you are using one of the supported versions of Ubuntu on a computer with an Intel Tiger Lake processor and have already installed yesterday's Intel Microcode update, it is recommended that you update the system to the new Intel Microcode version already in the main repository.

If you installed yesterday's Intel Microcode update and are experiencing failures to boot your system, you should use the kernel command line command listed above to prevent the firmware from loading and recover your system. Then update through the terminal with the following (is in one):

sudo apt  && sudo apt full-upgrade
