The sysctl is really just a hack. We should have a much better mechanism for
integrating our ACPI with the X11 desktop environments. GNOME/KDE/Mate don't
understand our sysctl and get confused easily.
You can turn it on by default, but I'm sure ACPI suspend/resume is not working
well enough like you say. How many laptops have you tested? For completeness,
how many desktops?
Suspend works for me. It's the resume part, on Dell and Acer systems at
least, that does not work at all.
There are bunch of ports kernel modules that will crash your system if you
suspend. VirtualBox is one of them.
* Save chip bugs that we should add workarounds for, we should be OK
to enter lower sleep states when idling. Flipping this may expose some
further crazy driver, platform or timer bugs, but they again likely
should be fixed.
They are still not fixed. Some of these problems are not in FreeBSD though and
I don't expect us to be able to work around them. We should try to identify
systems where C3 has surprising effects and blacklist them.
If there were an easy-to-run test, many would be happy to report
results.
