Subject: 2.5.74 X.25+LAPB still kills the kernel
Date: 11 Jul 2003 00:28:44 +0200 [thread overview]
Message-ID: <m37k6qhv8j.fsf@defiant.pm.waw.pl> (raw)
Hi,
No need to actually use X.25+LAPB, it's enough to just compile it in.
Linux version 2.5.74 (gcc version 3.2.3 20030422 (Red Hat Linux 3.2.3-4))
You do not need Ethernet either, it will oops with just loopback as well.
Serial console dump follows (details available on request in case someone
need them).
gw:/# ip link
1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
gw:/# ifconfig

ack
