I will. Thanks. Dave I have next thing. In kernel 2.6.13-rc6-git13 I observe relative very intensive emmiting some kernel messages. From yesterday logs: # grep "^Sep 12" /var/log/messages | grep kernel: | uniq | cut -d " " -f 6- | sort | uniq -c | sort -n | tail -n 2 509 svc: bad direction 268435456, dropping request 653 eth0: Happy Meal out of receive descriptors, packet dropped. As you see one of this two messagess occures avarange one time per ~two minutes. Second looks like some error in sunhme.c. eth0 it is: 0001:00:01.1 Ethernet controller: Sun Microsystems Computer Corp.
