Comment 230 for bug 274995

Interesting Robb. I have two installations of Intrepid on my laptop (which as I said has no Intel hardware, so should not be affected by any bios or driver bug suggested by Daniel Chen above). The one which I upgraded from Hardy does not show this fault, but the one which I installed from the CD does and was fixed by altering /etc/hosts to include localhost under ip6.

I compared the hosts files of the two installations however and found that the upgraded one which did not show the fault (Intrepid 1) also did not have the reference to localhost in the ip6 area. It did however have more hosts listed under the local domain IP at the top than the CD installation which did show the fault (Intrepid 2).

Intrepid 1 /etc/hosts (this installation does NOT show this bug and shuts down normally)

127.0.0.1 refd-lt localhost.localdomain localhost
127.0.1.1 fred-lt

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

Intrepid 2 (this fresh installation from CD DOES show the bug and hung during shutdown) Please note that the localhost in the second section was added to fix this bug.

127.0.0.1 localhost
