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. Happy Meal (rev 01)
