Suspend not working

[tim-m89]

Hi I would really like suspend to work on my freebsd machine. A small yet great power/time saving feature that windows and linux make use of with no trouble at all (relatively).

acpiconf -s 3

..Few seconds pass. Then appended to dmesg:

acpi0: device_suspend failed

I have latest bios.
Tried to figure out as much as I could by myself.
Tried asking for help.

Now what should I do?

Should not be a space between s and 3.

acpiconf -s3

Or is that a typo?

I'm not so sure that Windows & Linux work as perfectly as you assume. In my experience suspend/resume (on every platform except Mac) is at best a 2d6.

FreeBSD is probably always going to lag months or years behind Linux in desktop & laptop support.

But a couple of pointers: from what I gather suspend/resume doesn't work on SMP systems, and certainly doesn't work on every wonky ACPI implementation you can throw at it.

Should not be a space between s and 3.

acpiconf -s3

Doesn't matter. Many programs treat them as equivalent (I actually can't think of any right off the top of my head that don't).

Suspend/resume does work on SMP systems since a few months ago in FreeBSD 8, but yup, ACPI quality will be a factor. In my limited experience, Gigabyte push out horrible (read: windows only) ACPI implementations.

Seriously though I have had other freebsd acpi issues like a laptop that wouldn't power down but everything else worked fine. This is one area I would like to see freebsd borrow some techniques which I hope should be possible without infecting it with GNU.
