Hi all,
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.
Options used: -v /usr/src/linux/vmlinux (specified) -o /lib/modules/2.2.1/ (default) -k /proc/ksyms (default) -l /proc/modules (default) -m /usr/src/linux/System.map (default) -c 1 (default)

2 warnings issued. Results may not be reliable.
This IS repeatable. It happened after the following:
Warning: kfree_skb passed an skb still on a list (from fffffc00004053d4)

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.
