GPU crash - MMU fault detected during a GPU memory Read

Hello,

When dealing with GPU crashes our general recommendations are available in the docs here, though in later versions of this page there is additional information worth looking at because of the added information regarding why these crashes happen.

The most useful debug data usually comes from reproducing the crash with -gpucrashdebugging enabled (or r.GPUCrashDebugging=1) which will enable GPU breadcrumbs, NVidia Aftermath and DRED. And you’ll also want to test with the latest GPU drivers to ensure it’s not a driver issue that has been fixed.

On NVidia GPUs it can be helpful to get Aftermath crash dumps as outlined here that you can then open up in NSight and sometimes determine what shader and code was executing. GPU breadcrumbs and the commandlists output from DRED at the time of a crash can also provide hints as to what is going on.

If you can provide the logs with containing the breadcrumbs that can help us look for known issues with similar GPU breadcrumbs. And of course, providing a repro of the issue in a template project would be ideal. We have similar GPUs and may be able to repro the issue with the same driver.
