Hey Xishi,

You are using a really old driver, our current is 4.1.1 and 3.9 dates to over 3 years ago.  We have makes changes to support surprise removal that very well may address this issue.  Have you attempted to recreate this failure with the latest out of tree driver?

Thanks,
-Don <donald.c.skidmore@...el.com>
