Is Your UEFI Firmware Bugged? The Latest Kernel Update May Be the Culprit

Millions of Linux users may be affected by a firmware bug in their UEFI firmware that can cause their computers to boot slowly

The bug is triggered by the latest kernel update (version 5.16) and affects computers with Trusted Platform Modules (TPMs)

If you've noticed your computer booting more slowly than usual after installing the latest kernel update, you may be a victim of a firmware bug in your UEFI firmware. The bug, which is triggered by the latest kernel update (version 5.16), affects computers with Trusted Platform Modules (TPMs).

TPMs are hardware security chips that are used to store cryptographic keys and other sensitive information. They are often used in conjunction with hardware-based security features, such as fingerprint scanners and facial recognition. However, a bug in the UEFI firmware can cause the TPM to malfunction, which can lead to slow boot times.

The bug is caused by a race condition in the UEFI firmware that can occur when the kernel tries to access the TPM. This can cause the kernel to hang, which can lead to a slow boot time. The problem is compounded by the fact that many modern computers use UEFI firmware that is not up to date. This can make it more difficult to fix the bug.

There is no easy fix for this bug. The only real solution is to update your UEFI firmware. However, this can be a difficult and time-consuming process. If you are not comfortable updating your UEFI firmware yourself, you may want to contact the manufacturer of your computer for assistance.
