Different AMD instances require specific driver and kernel versions. When you purchase an AMD instance, use an officially supported operating system to ensure it includes the required driver and kernel versions.
OS support for different instance generations
Each AMD instance generation is compatible with specific operating system (OS) versions. Older operating systems may not fully support newer processor features from the AMD Zen architecture, released in 2017. The table below lists the OS compatibility for each AMD instance generation.
For best results, use a supported OS version from the following table.
If you must use an OS version that is not listed, consider using a different instance type that supports it, or find a suitable community image. For instructions, see Create an instance by using a community image.
If you use an unsupported operating system on an AMD instance, you assume all potential risks, including system instability and compatibility issues.

9th-generation AMD instances, based on the AMD Turin processor platform. |
|
|
| Running Ubuntu 16 or Debian 9 on a 9th-generation AMD instance (such as g9a) causes a kernel panic. Applying the patch in the linked patch document allows the system to start, but long-term stability is not guaranteed. |

8th-generation AMD instances, based on the AMD Genoa processor platform. |
|
|
| Running Ubuntu 16 or Debian 9 on an 8th-generation AMD instance (such as g8a) causes a kernel panic. Applying the patch in the linked patch document allows the system to start, but long-term stability is not guaranteed. |
7th-generation AMD instances, based on the AMD Milan processor platform. |
|
|
| Running Ubuntu 16 or Debian 9 on a 7th-generation AMD instance (such as g7a) causes a kernel panic. Applying the patch in the linked patch document allows the system to start, but long-term stability is not guaranteed. |
6th-generation AMD instances, based on the AMD Rome processor platform. |

| None |
General-purpose computing AMD instances that support multiple processor generations. |
|
|
| Running Ubuntu 16 or Debian 9 on the u2a instance family causes a kernel panic. Applying the patch in the linked patch document allows the system to start, but long-term stability is not guaranteed. |
