Severity |
Minor |
Symptom |
In the AMD environment of Android 15, after the system runs for four days under high load, the CPU load decreases abnormally and the container cannot be deleted. |
Root Cause |
There is a low probability that the amdgpu driver in kernel 6.6 encounters a page fault, causing the GPU to restart. After the application exits, the CPU load decreases. There is a low probability that the restart fails. In this case, the Android system processes that use GPU resources are suspended. As a result, the container cannot clear the processes and fails to be deleted. |
Impact |
This problem is caused by the amdgpu driver in kernel 6.6. According to issues in the upstream community, this is a common problem. AMD has not fixed this issue or provided a fix plan. |
Workaround |
This issue does not occur after the Mesa driver is replaced with the Mesa version built in Android 15. |
Solution |
Future efforts will focus on analyzing the differences between these two Mesa driver versions, with results to be submitted to the upstream community to facilitate a fix. |
