Using pavlov's modification of acpi/wakeup.S, the power will resume, as well as
the lights and what not, but keyboard/video are unusable(despite using hibernate
script). The modifications prevent suspend to ram from being usable, but only
with them and shutting off acpid does it not poweroff when I try to resume by
hitting an acpi key.

This is pretty much impossible to debug, may be BIOS problems. If someone has any ideas... I was mistaken, it does not actually power off. It SEEMS as though it is powered off, but if I hit a MM key at the top a second time, it reboots the machine. Created attachment 7147 [details]

So even with the changes in comment #1 the system is still reboot at resume, right? Created attachment 7270 [details]
debug patch
For such issues, I suspect Linux missed something, but haven't strong idea. The
attached patch tries to disable some devices at suspend time. Is it helpful?
Do you want me to try that patch and report something? if so, let me know specifically what you'd like me to do, as I am anxious to get this working:) As far as comment 1, I thought at first it stopped the "reboot" or whatever, but then It seemed most of the time, and only rarely, would it not do the reboot action. it seems to power off, but as soon as i hit power button or mm button on top, it reboots immediately. sorry, i read it wrong. I am at kernel 2.6.15.2. This is what I get on application. patch -p0 < sleepkernelpatch.patch patching file a/arch/i386/kernel/acpi/wakeup.S Hunk #1 FAILED at 11. Hunk #2 succeeded at 232 with fuzz 2 (offset 197 lines). 1 out of 2 hunks FAILED -- saving rejects to file a/arch/i386/kernel/acpi/wakeup.S.rej what should i modify in patch for it to work w/this kernel? For comment #1, you can manually change your code to align with the sample code of comment #1. please also try the debug patch I added. Thanks! :( applied your patch manually, same problem. on resume, seems to power down, but hitting MM key again reboots machine:( Did suspend ever work for you in Linux? On my Dell D800 Latitude, it did work in kernel 2.6.12, but it has not been able to wake up the video since then. So the system seems to still be asleep after suspend, but it is really asleep, except for the video. I don't know what an MM key is or why it would cause a reboot, but I think you need to rule out the possibility that your system is running except for the video While trying to debug this, I was following advice from many people and one advice was to fiddle the start-time kernel options for acpi. That's one of the changes in the kernel's documentation on dealing with waking up the video. I found certain combinations that would cause the symptom you describe. my recollection was that if I put acpi-sleep=bios. So I'd suggest you make sure you don't have that option in /etc/grub.conf. title Red Hat Linux ACPI

i only started trying suspend to ram again with recent kernels, as i couldn't
get it working when i last tried years ago.
MM keys are the multimedia tiny keys on top of laptop keyboard, and power button
does same thing.
when i try to resume hitting one of those, all lights go off, and there are no
sounds. it seems as though it is powered off. but, if you hit one of those
keys, it quickly turns on and reboots.
What is the current status of this bug? No idea, I sold this laptop over 1 year ago:) |
