G5 wake from sleep, configd, cups?

Message #1 - Posted 2005/05/10 - eur.van.andel

Hi all

I have a nagging problem with my G5 (1.8 GHz single, 512 MB). Sometimes, it won't wake up from sleep. That is: iTunes plays (via a script), the eject key works but the display stays dark. After calling Apple a number of times to no avail (reset PRM, reset SMU) I finally found a mention of this problem on an Apple forum:

http://discussions.info.apple.com/webx?13@671.dWnoaMq8SbT.3@.68aeb95d/0

Since I set my G5 to "never sleep", I am able to log in via SSH and poke around when it refuses to wake up, which happened this morning again. Indeed, ps -aux shows configd in the "Us" state, but is very hard to kill.
kill (pid) does not work
kill -1 (pid) shuts down my SSH conection and after that, I can't reach the G5 anymore by SSH.

Some log snippets from console:

It seems that the cups deamon is the culprit? Next time, I'll try killing that first.

How can I kill configd?
What could cause configd to be in "uninterruptible wait"? How do I get configd to snap out of it?

I recently upgraded to Tiger, but that did not help :-(
This G5 has this problem from the day I bought it.
