Hi friends!
I want to report on success and failure of suspend2disk and suspend2ram.
First, here the specs of my laptop/software: - kernel 2.6.7-mm5 - debian/sid - acer travelmate 654LCi - graphic: radeon mobility m7 (7500)
What is working:
- Suspend2Disk via pmdisk (echo -n disk > /sys/power/state) Nice thing is that it even works with uhci and ehci compiled into the kernel AND X running with agp and dri AND radeon framebuffer. So this is really nice and suprising for me.
Interestingly, I have to stop mysql server, otherwise it wouldn't suspend (cannot stop tasks)
But generally, big thanks to the pmdisk developer(s), it is working great! Even multiple suspend/resume cycles etc. Only thing I am missing is some way of post-resume script.
- partial Suspend2Ram via mem > /sys/power/state Here all the usb stuff has to be compile modular and has to be unloaded, no radeon framebuffer and no X is allowed. Then suspend to ram works, resume too, but the video card is not initialized again. Black screen. But I can shut down.
What is not working: - S2R framebuffer X usb restoring of video output - general clock is completely wrong - where is a post-resume script (see below)
What I don't know/haven't tested till now: - wlan drivers (orinoco) - network drivers (b44) - acerhk working
So now here are my questions: - Is it possible to get S2R to the level of S2D without problems? - is there a way to get things done BEFORE the suspend (this I managed via the acpi script), but also AFTER the resume. I need this for fixing the clock and starting mysql and some more stuff probably
Best wishes
Norbert
