Public bug reported:
Hello,
This night one of our main servers went down due to a kernel panic. The
server is running stock Dapper LTS with LAMP stack, postfix, and amavisd
with spamassassin. The stack trace is as shown below.
Could someone with the right expertise see what is going on here? And
where this bug should be filed?
