Subject: networking oops after resume from s2ram (2.6.28-rc6)
Date: Fri, 28 Nov 2008 22:15:40 +0100 [thread overview]
Message-ID: <20081128211538.GA6750@joi> (raw)
Hi
Sometimes after resume from s2ram networking doesn't work, so I restart it by
/etc/init.d/net.eth1 restart. Recently it started to lock up my box completely,
but today it oopsed only (and killed my keyboard, so I had to save dmesg with
mouse :D).
It looks like it tries to use netconsole without working network interface...
