Hi,
The error only able to inform you that the component which resides on bus 126 device 0 function 3 is not functioning correctly or having an issue.
To identify the component, you may need to login into iDRAC and navigate to System > Hardware Inventory. Under PCIe Devices, you should be able to identify the Bus, Device and Function number. This will help you match the identification of bus 126 device 0 function 3. Alternative, you can try checking the iDRAC log to see if there are any traces of the device having issue.
