Suspend and Resume Update!

Good News for Solaris users:

Suspend and Resume is working on many laptops!

With recent putbacks to Solaris, Suspend to RAM is functioning on many more laptops. Driver support is growing, some core bugs have been fixed, and the GUI tools have been fixed/enabled to use the feature!

Solaris build 100 was the synchronization point for bugs and feature improvements so that not only are all Sun x64 workstations supported, but 11 laptops are also officially supported. I even have a high degree of confidence that there is even a longer list of laptops that would also work, if enabled by the methods described in Suspend and Resume, How To!

All but one of my Solaris x64 machines are are now configured to and regularly suspended (one has full PM support configured, and if left unattended, will suspend on it's own). The one that doesn't is using a framebuffer from a vendor that doesn't seem to think it is important enough to help make Suspend and Resume work on their hardware, so there is a good possibility that I will be changing that framebuffer.

There still is a lot more work to be done: fix/update more drivers, add more platform support, implement Suspend to Disk (S4), and add all of this support into xVM! But this feature is now far more mainstream than has previously been in Solaris, so start using it, and let us know how it is going. Comments can be made to either (or both) of the Laptop, or Power Management communities. You can also get involved by joining the these communities and contributing ideas or code. The Power Management community is supporting the Suspend to Disk and Storage Power Management projects, and comments and/or code is very much welcome.

So get involved, and help make Power Management the best possible.

And while you are at it, pull out a New Belgian Abby Ale! New Belgian Brewing in Colorado has a history of creating innovative good beer. And this is probably the closest I have had to an actual Belgian Abby-style ale. A rich malty taste with the distinct esters known in Belgian beer, and a nice spicy finish without strong alcohol overtones (though there is definitely alcohol). A wonderful US alternative to typical Belgian imports.

New Belgian while Suspended! A great way to spend the evening! Too bad the machine will resume quickly in the morning and get you back to work.

Great stuff! But, where can I find the list of supported systems?

I didn't originally intend to post the "current" list, as I epect it to change.

However, as of the date of this comment (10/01/2008), the list is:

TOSHIBA TECRA M8
TOSHIBA TECRA M9
TOSHIBA TECRA M10
TOSHIBA TECRA A9
TOSHIBA Satellite A205
TOSHIBA PORTEGE R500
LENOVO 64608VU
LENOVO 889703U
Sony Corporation VGN-CR490N
Dell Inc. Latitude D630
Dell Inc. Precision M4300
Sun Microsystems Ultra 24
Sun Microsystems Ultra 40 Workstation
Sun Microsystems Ultra 20 Workstation

Check the Laptop or Power Management communities on opensolaris.org, as sometime in the near future, I expect to see a regularly updated list.

Hi,

This is just fantastic stuff !
Would it be possible to contact Lenovo themselves so that you may support all of there range as its rather small and I am sure IBM would be willing to help more then anyone else I could think of..

Thanks,
Edward O'Callaghan.

Hi,

I tested this on my Fujitsu Siemens Amilo Pi 1505 (OpenSolaris 2008.05 snv98). Suspending crashed the system completely, another try worked but the backlight of my monitor stayed off.

when I run the command "# uamdin 3 1", I got such msg:
uadmin: can't turn off auditd
uadmin: Operation not supported

any idea? Thanks

I have suspend/resume more or less working on my dv9500 HP laptop. It has a dual core Turion, broadcom wifi (ndis 1.2.1) and is running nv104. It worked perfectly prior to about nv101. Currently, there is a caveat where it seems to get stuck in an ACPI response loop upon resume. Most of the time, plugging/unplugging the power cord breaks it out of the loop and the resume succeeds.
