I received feedback and a temporary workaround from Nvidia tech support (see below). I have followed these instructions and so far haven't experienced another crash. It would be great if others could report back with their findings / experience. Note that this will allow users to update to the latest drivers.
This is a known issue that our development team is actively investigating. Our development team have root-caused the issue and will be implementing a solution in future driver update. At this point I don't know which driver release will have this fix. Until we can get this resolved in a driver update there is a workaround to this problem with our current drivers. Development indicated that enabling Message-Signaled Interrupts (MSI) does resolve the problem. Consider the steps below to enable MSI after installing the latest graphics drivers and that should help with the issue. You'll need to enable MSI for each GPU.
1. Download the MSI Utility v2.0 zip file here:https://github.com/CHEF-KOCH/MSI-utility/releases
2. Open the zip file and then extract "MSI_util_v2.exe" to your local system.
3. Right-click the "MSI_util_v2.exe" and Run as administrator.
4. Enable MSI for each GPU listed.
5. Restart the system.
Until we can get the fix into a driver update you'll need to apply this workaround with each new driver update. We are working to get this fix into our drivers as soon as we can. Hope this helps. Let me know if you have any further questions.
Best regards,
Thanks for the info!
Have tried this today and so far, the machine is rendering a C4D-scene (with 7* GTX 1080ti) without crash for over 2 hours. Have not been able to do that yet, so looking good. Fingers crossed, I will post back with results.
