Getting two types of console messages when using pktgen and 2.6.11 and the
pktgen-conf-1-1 script.

1. Errors from IPV4

KERNEL: assertion (!idev->ifa_list) failed at net/ipv4/devinet.c (122)
KERNEL: assertion (!idev->mc_list) failed at net/ipv4/devinet.c (123)

2. Cliff is getting this with e1000 and pktgen-conf-1-2
 looks like calling schedule_timeout with lock held.
