ACPI failures on non-Intel hardware
http://bugzilla.kernel.org/show_bug.cgi?id=3691 describes a fairly serious ACPI failure. Attempting to wake up from S3 suspend seems to result in the system rebooting without any wakeup code being run. I've seen this behaviour on two machines, and had it described to me on a third. Interestingly, all the machines in question were non-Intel hardware - one is a VIA C3, and the other two are Athlon XPs (not Athlon64s). On the test machine I have here, FreeBSD behaves identically to Linux (seemingly successful suspend, reboot on wake) and Windows suspends and resumes correctly.
The fact that I've only seen this on systems that didn't have Intel motherboard chipsets makes me wonder whether there's something going wrong during the suspend code that happens to work by chance on Intel (and a few other) chipsets, or alternatively whether these chipsets manage to fall outside the specs slightly. Any ideas?

Very interesting! (Thanks for testing FreeBSD also.) I hadn't noticed the common thread in S3 error complaints except that the three classes are 1. goes to sleep and immediately wakes, 2. resets while going to sleep or waking up, and 3. goes to sleep and never wakes.
One thing you should try is disabling various methods (like _SST) and see what happens. I think _BFS should be run before _SST since the 7.3.5 says no other method should be run before _BFS. Also, enabling BM arb after sleep may affect things.
I'll test suspend/resume on my new EPIA-M at some point soon.

See some Acer machine if you want to see similar failure on Intel system...

I thought that case crashed /inside/ the wakeup code, rather than rebooting before any of it was run?

I saw some Acer (do not recall model #, sorry, and it was probably prototype, anyway) where it died before wakeup.

Do you remember whether it had an Intel motherboard chipset, or was an Intel CPU on something like an ATI chipset?

I think it was centrino (=> Intel chipset), but it was quite long ago. Another Acer should pop up around me in ~1 month...
