Hi. Sorry for the late reply. I applied the patch (so now my
drivers/net/loopback.c around line 173 looks like:
for (i=0; i < NR_CPUS; i++) {
if (!cpu_possible(i))
continue;
lb_stats = &per_cpu(loopback_stats, i);
stats->rx_bytes += per_cpu_ptr(loopback_stats,
i)->rx_bytes;
stats->tx_bytes += per_cpu_ptr(loopback_stats,
i)->tx_bytes;
stats->rx_packets += per_cpu_ptr(loopback_stats,
i)->rx_packets; stats->tx_packets +=
per_cpu_ptr(loopback_stats, i)->tx_packets; }
return stats;
(and if that is the patch, then I get --with extra debugging in the
kernel):

I will try (any patches), but unfortunately, my turnaround time will
(likely) be delayed about 20 hours from this post (working long hours
lately).
Thanks for all replies.
