Hi,

The "ctf error" you're experiencing, followed by a reboot or shutdown, strongly suggests a problem with the stability of the GPU or its power delivery under load.

Here are a few things you should check:

1. Power Supply:

• Adequacy: The AMD FirePro S7150x2 can draw a significant amount of power. Ensure your PowerEdge r730xd's power supplies are sufficient to handle the additional load. Check your server's power calculator and the card's specification to determine the total wattage needed. If you have redundant power supplies, are both of them working correctly?
• Connections: Double-check that the dual power cable is securely connected to the GPU and the server's power distribution board. Also, make sure that the power cables are fully inserted into the GPU's power connector.

2. Cooling:

• Airflow: Make sure the server has adequate airflow to cool the GPUs. The R730xd is designed with specific airflow pathways; ensure there are no obstructions.
• Ambient Temp: Verify that your server environment is not too hot. High ambient temperatures can exacerbate heat issues and cause components to fail.

3. BIOS/Firmware:

• Latest Updates: Ensure your server's BIOS and iDRAC firmware are up to date. Sometimes, older firmware versions have bugs that can cause unexpected issues with PCIe cards.

4. PCIe Slot:

• Slot Configuration: Verify that the PCIe slot configuration in the BIOS is set to the correct speed and lane width. Check the server's documentation to confirm that the slot is compatible with the GPU's PCIe version.
• Slot Functionality: Although the slot appears to be working initially, there may be a hardware issue. Try testing the GPU in another slot if possible.

5. Driver/Software:

• GPU Drivers: While the issue seems to be crashing the system, verify the proper drivers are installed in the VM.
• Pass-Through Configuration: Recheck your KVM pass-through configuration settings in the hypervisor. There may be a specific setting to be enabled/disabled, and the VM should have adequate resources configured to the allocated GPU.

6. Hardware Issues:

• GPU Health: It's possible that one or both GPUs in the S7150x2 have a hardware problem. If you have another system, try testing the GPUs there if possible.
• Power Cable/Connectors: The dual power cable could be faulty. Try another cable, if possible.

7. "ctf error":

• Error Context: Usually, a "ctf error" is related to the Component Transfer Framework. It can be triggered by device driver issues, power, or hardware issues.
• Error Logs: Review the system's event logs, iDRAC logs, and hypervisor logs for more detailed error messages.

I would suggest starting with the power and cooling checks, and then moving on to firmware and driver updates. If those don't resolve it, then you may have a hardware issue
