Howdy,
My HTPC goes to sleep (S3) and resumes just fine (via RTC or WOL).
My problem is that I need to know whether it woke up from RTC or WOL and I
find nothing in dmesg that gives me a clue for the wakeup reason.
Is it something that I can get from somewhere?
Thanks,
Marc

http://marc.info/?l=linux-acpi&m=133478932527097&w=2 is a similar sort
of request; maybe something similar could be done.

Thanks for the patches.
Do you know if either is likely to ever make it to mainline?
Thanks,
Marc

I'm planning on pestering people until they do. The button wakeup one
has been acked so I assume that one is close.
Waiting for comments on the rtc-cmos patch.
