Hi,
I've just seen the following assertions pop out of one of my servers
running 2.6.16.9 with grsecurity. I've searched the archives of LKML
and netdev and I've only found posts relating to 2.6.9, after which
some related bugs were fixed... It looks like these bugs are related
to e1000, which is the driver I'm using. The system was running 24
days before these appeared and it's still running absolutely fine.
May 16 09:15:12 baldrick kernel: [6442250.504000] KERNEL: assertion (!
sk->sk_forward_alloc) failed at net/core/stream.c (283)
May 16 09:15:12 baldrick kernel: [6442250.513000] KERNEL: assertion (!
sk->sk_forward_alloc) failed at net/ipv4/af_inet.c (150)
baldrick bootc # ethtool -k eth0
Offload parameters for eth0:
rx-checksumming: on
tx-checksumming: on
scatter-gather: on
tcp segmentation offload: on
Many thanks,
Chris

I guess just disable TSO or use latest kernel from git, it has a fix for this.
