I've tried a handful of different 2.6 kernels (including 2.6.6-rc3.mm1 for kicks) all of which exhibit the same behaviour. On the whole, ACPI works flawlessly and returns incredibly detailed information about every part of the system. I can enter S3 sleep by "echo -n 3>/proc/acpi/sleep" or "echo mem>/sys/power/state" and the laptop switches to a console vt, prints a few things which seem reasonable about going to sleep, and powers down. The wireless goes out, and the power light flashes in a manner I'd expect from a sleeping laptop. If I reactive the laptop (usually with the power button) the wireless light comes back on, the power light goes green and the fan spins up. But nothing else. The screen remains black and un-backlit, the keyboard doesn't respond to events (caps lock key doesn't light the light and typing "find /" doesn't produce disk activity) and afaict the network card doesn't come back either (I can't ping the machine from elsewhere). So it almost entirely seems to be not waking up from sleep. I've tried the various tricks outlined in the kernel documentation, an all-modules kernel with no framebuffer booted with init=3D/bin/bash still produces the same behaviour. I'd like to get this working; are there any further tricks I could try? If not, what's the best way to go about starting to debug *why* this doesn't work? Thanks, Scott (Please Cc: me, I'm not subscribed) --=20 Have you ever, ever felt like this? Had strange things happen? Are you going round the twist? --=-bOSx8WSNKKauvi1NXwJO Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) iD8DBQBAmSMMIexP3IStZ2wRAsx8AKCkSVRc4Ha4W/Dnayq7AFVPI71r5QCeJQwK LgAqLKXvo3xgRUD9IlMa7PA= =+NYk -----END PGP SIGNATURE----- --=-bOSx8WSNKKauvi1NXwJO-- ------------------------------------------------------- This SF.Net email is sponsored by: Oracle 10g Get certified on the hottest thing ever to hit the market...
