[wdmaudiodev] NMI parity error on XP shutdown

Hi,

I'm wondering if anyone else has seen something like this....

Keeping the audio card and system hardware the same, when we moved from W2k to XP we started seeing BSOD when shutting down the OS. The bluescreen would say something like Memory Parity NMI error.

Our audio hardware is PCI bus mastering and writes to system memory every 50ms or so. Could that cause a NMI memory parity error ? And why ?

I do know that if I turn off the bus mastering writes that happen every 50ms, the problem goes away.

Anyone else come across something similar ?

- Andrew
