[Fwd: Re: Dell Inspiron 510m sleep states S3/S4 not working]
I have reports that Linux works for S3 on these machines but FreeBSD does not. The Dell Inspiron 510M at least has a problem where the write to PM1A in hwsleep.c resets the system instead of entering S3. I heard that Linux had similar problems in the past but now works. Can someone let me know what was going on?
Thanks much,
Nate

Easiest way to test for resets is to stick this loop in the C code, pushing it farther down until you identify the line of code that resets instead of hanging.
hang: goto hang;

Try this in
AcpiEnterSleepState().Been there, done that. See

I just did some testing just to make sure that my system resets on the same line. Sadly that is the problem, writing PM1A resets the machine.
I also compared the code with hwsleep.c from linux 2.6.10. They almost exactly the same, except for at one point but that should only affect S5. Everything else is the same.
