As reported by many users, Intel WiFi chips such as 3945ABG and the later 4965 may experience CPU spikes due to DPC activity.
This is typically experienced as:
- Audio stuttering.
- Uninterrupted dumping of 5010 events with NETWLV64.SYS as source. (Probably NETWLV32 also, depending on architecture).
Event information: http://technet.microsoft.com/en-us/library/cc727742(v=ws.10).aspx
Event data that appears:
The description for Event ID 5010 from source netwlvXX cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.
If the event originated on another computer, the display information had to be saved with the event.
The following information was included with the event:
\Device\NDMPx
I've personally been bugged with this event on Windows 8 and 8.1 only with default Microsoft drivers, and with newer Intel drivers. My system is a Lenovo R61i with updated Core2 Duo CPU, 3GB RAM and i945 system chipset. An old and standard configuration.
