I'm running f13 on a laptop that is configured to lock the screen
after the lid is closed. This used to work under f12, but has never
worked under f13. Instead I see logs similar to the following in
/var/log/messages:

Jul 17 17:54:20 watson kernel: INFO: task kacpi_notify:23 blocked for
more than 120 seconds.
Jul 17 17:54:20 watson kernel: "echo 0 >
/proc/sys/kernel/hung_task_timeout_secs" disables this message.

Have i misconfigured something or is this a bug? This is on a fully
updated system, so kernel-2.6.33.6-147.fc13.x86_64
