Summary0005643: CreateFile may fail (NetDCUA9 only)
DescriptionCreateFile may fail (NetDCUA9 only)
Steps To ReproduceCustomer ALS reports that ca. 1/1000 CreateFile may fail, than a reboot is required:
    for(int i=0; i < 4; i++)
    {
        TCHAR t[32];
        wsprintf(t, _T("AIN%d"),i);
          HANDLE hAIN = CreateFile( t, GENERIC_READ, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL );

        if( hAIN == INVALID_HANDLE_VALUE )
        {
            RETAILMSG(1, (TEXT("*** AIN%d ok\r\n"), i));
            CloseHandle(hAIN);
        }
        else
        {
            RETAILMSG(1, (TEXT("*** AINERRROR %d\r\n"), i));
        }
    }
Additional InformationThere must be an issue reading data via AC97 via SSI module - not found!
Use workaround to read IDs while initialisation (read eight times - if required), if we got no correct result we can be sure chip is not available.
Same issue while measure are avoided by the the mean over a collection of data.
