How To Fix the TSC_DEADLINE Firmware Bug in Ubuntu: A Guide for Newbies

Ubuntu 13

If you’re new to Ubuntu, you may have come across an error message that reads “[Firmware Bug]: TSC_DEADLINE disabled due to Errata; please update microcode to version: 0x52 (or later)”. This can be a daunting message, especially for beginners. But don’t worry, this guide will walk you through the steps to fix this bug.

Understanding the TSC_DEADLINE Bug

Before we delve into the solution, it’s important to understand what this bug is. The TSC_DEADLINE is a timer mechanism in modern processors. A firmware bug in this feature means that there’s an issue with the software embedded in your computer’s hardware. The error message is asking you to update your microcode, which is a low-level code that helps your processor operate correctly.

Step 1: Install intel-microcode

The first step in resolving this bug is to install intel-microcode. This is a package that provides updates for Intel CPUs. You can install it via the terminal with the following command:

sudo apt-get install intel-microcode

Here, sudo gives you superuser privileges, apt-get is the package handling utility in Ubuntu, and install is the command to install a package. intel-microcode is the package you’re installing.

After running this command, reboot your system to see if the bug has been resolved.

Step 2: Update Your BIOS

If the bug persists after installing intel-microcode, you may need to update your BIOS. The BIOS (Basic Input/Output System) is the program a computer’s microprocessor uses to start the computer system after it is powered on. Updating your BIOS can often resolve firmware bugs.

The process to update your BIOS varies depending on your computer’s manufacturer and model. Consult your computer’s documentation or the manufacturer’s website for specific instructions.

Step 3: Check for Existing Solutions

Before attempting other solutions or reporting the bug, check if there are existing solutions on platforms like AskUbuntu or Ubuntu Forums. You can search using the key text from the bug message to find relevant discussions.

For instance, this specific bug has been reported as bug 1724650. You can follow the suggested solutions provided by other users in the comments section of the bug report.

Step 4: Reporting Bugs

If you can’t find a solution or if the bug hasn’t been reported, you can report it to the Ubuntu community. The AskUbuntu post How do I report a bug? provides a detailed guide on how to report bugs effectively.


Remember, it’s always important to backup your data before making any significant changes to your system, especially when updating the BIOS. While the TSC_DEADLINE bug might seem intimidating at first, with a little patience and the right steps, you can resolve it and continue enjoying your Ubuntu experience.

How can I check if the TSC_DEADLINE bug has been fixed after installing intel-microcode?

After installing intel-microcode and rebooting your system, you can check if the TSC_DEADLINE bug has been fixed by running the following command in the terminal:

dmesg | grep microcode

If the bug has been successfully fixed, you should see a line that mentions the microcode update.

Can I install `intel-microcode` on non-Intel CPUs?

No, intel-microcode is specifically designed for Intel CPUs. If you have a non-Intel CPU, you should check if there are any microcode updates available for your specific CPU manufacturer and model.
