(!sk->sk_forward_alloc) assertation failure in 2.6.26-rc5

FYI saw this on a system which was running 2.6.25rc5 for quite some time.

It might have been related to me restarting the NFS server (not 100% sure)

KERNEL: assertion (!sk->sk_forward_alloc) failed at /home/lsrc/misc/linux/net/ipv4/af_inet.c (157)

Happened only once so far.
