That was my feeling Moshe, thanks for checking.

Anil, which card and drivers are you using exactly?

You should probably contact your card vendor and check if they have a
fix for the issue, which seems more like a bug on their implementation
of the embedded switch, the card or the driver.

Best regards,
Miguel  Ángel.
