I have a hand-compiled kernel 2.6.8.1 (patched with bootsplash, ACPI and swsusp2 patches from 10 days ago) that I am using. Most drivers are compiled as modules except for framebuufer, bootsplash, swsusp2, etc. I am able to hibernate my laptop (i.e. suspend to disk) fine using swsusp2. I am also able to suspend my laptop to RAM just fine (passing acpi_mode=s3_bios to kernel). My problem is waking up from an S3 suspend to RAM sleep. When suspended, the "sliver / crescent moon" LED comes on indicating that the laptop is sleeping. When I close the lid and reopen it, the laptop tries to wake up and I hear a beep. But nothing shows up on the display. The crescent moon LED is also no longer illuminated. I know that the laptop has woken up because at this stage I can press the power button and initiate a swsusp2 suspend. When I restart I am able to wake up the state that was suspended to disk. My questions: 1. Has anyone got waking up from S3 suspend to work properly on a G40? If so, how? 2. I upgraded to the latest BIOS on IBM's support site. If this BIOS is still broken, I guess I need to upgrade my DSDT table. Unfortunately, the documentation I read refers me to an iasl compiler that I cannot find at the indicated site: http://developer.intel.com/technology/iapc/acpi/downloads.htm 3. Is there a way to invoke swsusp2 on S4 suspend? I tried my experiements above with only acpi modules loaded and nothing else in single usermode (with pcmcia, usb, etc., unloaded). Thanks.
