Hi,

The machine configurations is as follows:

1. T5500 Precision
2. BIOS version: A18
3. OS: Ubuntu 20.04 LTS
4. Graphics card: Nvidia Quadro 5000

The machine was working fine till I added a HP NC375T PCIe Quad Port network card then machine started giving following error:

Alert! Error initializing PCI Express bridge to PCIX

Strike the F1 key to continue, F2 to run the setup utility

Press F5 to run onboard diagnostics

 

I tried removing the quad port card but the error does not goes away. Also F1 boots fine and the network card works fine, F2 leads to BIOS and all settings seem fine and see no error. F5 runs for few minutes and return no errors.

Any idea or pointer how to make this error go away?

Thanks.
