Bug#356074: linux-image-2.6.15-1-686: assertion failures in net/core/stream.c and net/ipv4/af_inet.c
Package: kernel
Version: 2.6.15-8
Severity: important
Hi,
here is the problem:
$ dmesg
[...]
KERNEL: assertion (!sk->sk_forward_alloc) failed at net/core/stream.c (279)
KERNEL: assertion (!sk->sk_forward_alloc) failed at net/ipv4/af_inet.c (148)
I have found similar reports here:
http://lkml.org/lkml/2006/2/7/53
http://oss.sgi.com/projects/netdev/archive/2004-11/msg00608.html
with comments from kernel developers, but nothing conclusive.
Here is the harware on this server:
