Thanks for the dump.
I believe I've found the problem and will get a patch to Jeff shortly.

Did you have that patch posted already?

It is not posted yet. Don got the patch to our testers and they are doing a quick validation on the patch before I post it to netdev.

I can send you the patch, so that you can assist in letting us know if it resolves the issue.

Hi Yinghai,

I was hoping we could have had this patch pushed upstream sooner, but we have quite a few in our internal queue right now.

If this doesn't solve your issue please let me know.

Thanks,
-Don Skidmore <[email protected]>

After freeing the rings we were not zeroing out the ring count values. This patch now clears these counts correctly.
