I just got the following kernel oops. I think it is related to my
earlier post. It was copied by hand, so I can't guarentee its accuracy, but
I think that I got it right.

Subject: Warning: kfree_skb passed an skb still on a list
Hi,
When I run a benchmark against a Linux V2.2.1 kernel (No SMP) compiled
for Alpha with egcs-1.1.1, I receive the following warning:
Warning: kfree_skb passed an skb still on a list (from fffffc00004053d4).
Should I be scared?
The program that triggers this runs on a Digital Unix box, and pounds on the
Alpha/Linux httpd server (apache) over a FDDI link. Netstat shows many
lines similar to the following:
tcp 0 0 10.0.0.1:www 10.0.0.3:2793 TIME_WAIT
This is VERY reproducable. My config file is included.
If you need more information, drop me a line.
