Description Ted Logan 2006-01-13 07:56:46 UTC
Although resumes fine in XP, in Linux, after you suspend to ram, if you wish to resume, if you hit power button or any acpi button, it seems for a split second as though it is resuming, but then shuts off instantly. Laptop with Athlon XP 1.67 processor.
Comment 1 Ted Logan 2006-01-17 12:12:33 UTC
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. --------------- #define BEEP \ inb $97, %al; \ outb %al, $0x80; \ movb $3, %al; \ outb %al, $97; \ outb %al, $0x80; \ movb $-74, %al; \ outb %al, $67; \ outb %al, $0x80; \ movb $-119, %al; \ outb %al, $66; \ outb %al, $0x80; \ movb $15, %al; \ outb %al, $66; ALIGN .align 4096 ENTRY(wakeup_start) wakeup_code: wakeup_code_start = . .code16 BEEP 1: jmp 1b movw $0xb800, %ax movw %ax,%fs movw $0x0e00 + 'L', %fs:(0x10) ---------------------------

This is pretty much impossible to debug, may be BIOS problems. If someone has any ideas...
Comment 3 Ted Logan 2006-01-18 07:23:31 UTC
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.
Comment 5 Shaohua 2006-02-07 18:50:02 UTC
So even with the changes in comment #1 the system is still reboot at resume, right?
Comment 6 Shaohua 2006-02-07 18:54:47 UTC
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?
Comment 7 Ted Logan 2006-02-07 19:36:08 UTC
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.
Comment 8 Ted Logan 2006-02-07 19:39:29 UTC
sorry, i read it wrong. I am at kernel 126.96.36.199. 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?
Comment 9 Shaohua 2006-02-07 20:20:03 UTC
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!

Comment 11 Ted Logan 2006-02-08 10:23:12 UTC
:( applied your patch manually, same problem. on resume, seems to power down, but hitting MM key again reboots machine:(
Comment 12 Paul Johnson 2006-02-10 06:52:42 UTC
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 root (hd0,1) kernel /boot/vmlinuz-2.6.15-wake ro root=/dev/hda2 pci=usepirqmask resume2=swap:/dev/hda5 idebus=100 nolapic pci=noacpi noapic 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?
Comment 15 Ted Logan 2007-06-04 12:56:18 UTC
No idea, I sold this laptop over 1 year ago:)
