User Response
Complete the following steps:
- Check the log for a separate error related to an associated PCIe device and resolve that error.
- Check the Lenovo support site for an applicable service bulletin or firmware update for the system or adapter that applies to this error.
- If problem persists, move the adapter to a different slot. If a slot is not available or error recurs, replace the adapter.
- If the adapter was moved to a different slot and the error did not recur, verify that this is not a system limitation. Then replace the system board. Also, if this is not the initial installation and the error persists after adapter replacement, replace the system board.
