Hi Geoff.

Quoting everything for the list.

I had seen this before posting.

My problem is that, whereas I can wake up the machine using WOL after 
power has been completely shut off, I can't do it when the machine has 
been shut down in the normal way.

I've seen reports of the problem being the other way around (WOL works 
after the machine has been shut down but not after it's been powered 
down), but not of my particular combination of symptoms.

I've also seen Joe Henley's recommendation, which is essentially not to 
shut the machine down but rather put it to S3 sleep. Thanks for that 
Joe, I'll report back when I've tested it.

Meanwhile I remain interested in the question as to how to shut this 
machine down in a way that will enable it to be WOL-ed.

(Reminder: it's a diskless root-on-nfs machine).

Thanks, Jan
