Hi, I found your post... my system: DELL Inspiron 3800 (BIOS A17) SuSE kernel 2.6.8-24-default powersave-0.9.19-2 SuSE 9.2 (my native language: german :-)
observations about my configuration: 1. i tried writing states 1-3 to /proc/acpi/sleep, and that seems to work as expected, putting it to sleep. when it wakes, the screen won't come back, i don't think sysrq keys work, and i end up holding the power button to get it to shutdown. Hm, I have all my screens dark after STR/STBY , except the X-one. My machine is running fine, only without screen. Did you find a fix for this?
Thanks Markus I don't have these other problems:
2. swsusp works, and wakes properly the first time. it leaves the clock out of sync, the ps2 mouse doesn't work until reload of the psmouse module, but the software-ejected pcmcia nic actually automatically reinserts itself. i can deal with scripting up these things, but i'd be interested in good ways to hook the wake event.
on the second swsusp suspend/wake, bash oopses the kernel immediately upon waking. updated will oops a few minutes afterward.
this all shows alot of promise, but i'd like to know how to clear these things up. i've been anxiously awaiting a new kernel to see if it's cleaned up.
thanks.
