Mc-err on Jetson Xavier NX 16GB module

We used to use 8GB module, there was no problem. After changing to 16GB module, the device can boot up normally,
but I got a mc-err issue after running for a period of time. Searching the forums, someone is having similar problems with DLA, but we are not using the DLA feature.
The following is the log of the occurrence of the problem, and I hope someone can help analyze the cause, thank you!

SDK: Tegra186_linux_R32.5.1 + patch: NX-16GB-R32.5.1 -overlay.tbz2
