Date: Sat, 13 Sep 2008 20:30:33 +0200 From: Stefan Ehmann <shoesoft@gmx.net> To: freebsd-stable@freebsd.org Subject: ipfw uid regression Message-ID: <200809132030.34870.shoesoft@gmx.net>
next in thread | raw e-mail | index | archive | help
I've updated from 7.0 to RELENG_7 today.
ipfw uid rules have caused problems in the past with PREEMPTION enabled.
This was fixed in 7.0, at least for me.
In RELENG_7 the old problems are back: Total freeze within some
seconds/minutes after the first network access.
With WITNESS I get a LOR, see at the end of dmesg.
