Subject: [OOPS] [2.6.0-test5] HTB QoS crash...
Date: Thu, 25 Sep 2003 00:52:45 +0200 (MEST) [thread overview]
Message-ID: <16014.1064443965@www46.gmx.net> (raw)
I bring my ppp0 interface up, setup various traffic shaping and policing
filters [1] (Bert Hubert's excellent 'wondershaper').
When I 'killall pppd', the kernel crashes [2].
