Description yilong, sun 2012-02-28 02:48:47 UTC 
when we make fri2 into S3 standby mode with command “echo mem > /sys/power/state”. we can still ping it from remote machine.

Testing Env:            
meta-yocto        = "master:d8b3718303c3d56394c722059f1a73bd79131d0a"
meta-intel        
meta-fri2         = "master:1ca68394faf33416f2aabee27323da7510ad6609"

Reproduce Steps:
1. build image and make USB live boot. 
2. boot ths image with command "boot psplash=false text 3 no_console_suspend"
3. Run command "echo mem > /sys/power/state" to make system into S3 mode

Moving back to 1.2 as the meta-intel BSPs are being updated over the next few weeks to accompany the 1.2 release.

The device successfully goes to sleep using the current 3.2 kernel using the "echo mem >/sys/power/state" command. It does not however, wake up :-) There isn't a power button on the device. Testing perhaps with wake-on lan or similar is required.

Can you confirm that the current build no longer exhibits this behavior?

Also, there are some power settings in the BIOS. My device had suspend to ram disabled. I enabled it to try the test.

Laurentiu, can you please have a look at this with the current 1.2 BSP release and let me know if we can close this out (works for me) or if we need to do more work for 1.3.
Comment 5 Darren Hart 2012-08-13 15:45:22 UTC 
According to the errata, the FRI2 hardware doesn't support S3. Suggests there is nothing we can do here...
