Subject: oops with 2.6.8.1 (kswapd?)
Date: Tue, 07 Sep 2004 09:20:32 +0200 [thread overview]
Message-ID: <413D6140.6020208@bio.ifi.lmu.de> (raw)
Hi,
I just detected a kernel oops in my /var/log/messages, but I've no idea
what caused it... I didn't do anything special, or ran out of memory
or swap space or sth.
Here are the messages and the output of ksymoops. Does it tell someone
what could be wrong?
