No, I am using a "book-PC" type machine [small Celeron] dmesg attached
I reinstalled my shaper box with 4.2 release today and cvsuped to
4.2-stable.
The strange thing is that if I turn on verbose logging (via sysctl) but
don't turn on verbose_limit, dmesg seems to get corrupted. If I have
verbose_limit set to say 10, dmesg works and does not get overridden
with log messages from ipfw [which goes to /var/log/security]
This is what I have in my /etc/sysctl.conf
net.link.ether.bridge_ipfw=1
net.link.ether.bridge=1
net.inet.ip.fw.verbose=1
net.inet.ip.fw.verbose_limit=10
So, it seems some combination of verbose logging and non setting of
verbose limit [or the default setting of verbose limit] is causing this
problem
Hope this helps, Regards, Yusuf
