Distribution: Fedora core 1
Hardware Environment: Dell 5150 inspiration bios A29
Software Environment: Default Gnome
Problem Description: /proc/acpi/sleep (any state) the system goes into standby
just fine, upon pressing power button to resume I get the following
Back to C!
i8042c: Warning: Keylock active
PM: Finishing up
PCI: Setting latency timer of device 0000:00:id.0 to64
PCI: Setting latency timer of device 0000:00:id.1
PCI: Setting latency timer of device 0000:00:id.2
System just sits there idle, after some time fan runs on high, keyboard
unresponsive, mouse and wifi card dead, have to do a hard reboot of the system
by holding power button down 10 seconds.
Steps to reproduce: have disconnected external mouse, wifi card and printer,
tried without an X server running and booted with "pci=noacpi" but the problem
persists. Same exact symptoms on either 2.6.0 or 2.6.1 kernel. Stock Fedora
kernel system resumes fine.

any luck with 2.6.3 -- it is working for me. thanks, -Len
Problem still occurs up to 2.6.3 here.
Symptoms are similar, but not identical.
Going to S1, I get the same messages, but actually going into the mode, the
LCD does not turn off. (I have the Radeon 9000 video card)
Going into S3, the LCD does not come back on, so no messages can be found
S4 actually works, so long as X is not running, and that may be related to
known DRI issues.
Just to add my 2 cents:
Similar behavior observed on my system:
Hardware: Dell 600m BIOS 09, w/ Centrino Wireless, ACPI enabled
Software: Stock Gnome + XFree86 188.8.131.523 + kernel 2.6.3
Only have tried S1, from X:
system goes into standby, screen goes to a console and does not go off.
(that's why I can see all the messages going into std-by and resuming)
Try to resume, I see the 3 messages "PCI: Setting latency ..."
and the system just hangs there.
Same problem here, however, my 5150 can resume from S1 if:
IO-APIC & Local APIC are enabled (or crashes at Back to C!)
ehci-hcd is rmmod'd
snd-intel8x0 (ALSA) is rmmod'd
Screen & keyboard are dead on resume from S3
I ran 2.6.7 + the latest ACPI patch on a Dell 5150 yesterday
and S3 resume worked except the video. Was running text-mode
console on NVIDIA hardware.
please test this patch and let me know if
wakes up the blank screen after resume.
i have tried everything possible to get this to work on the
5150. I have the latest bios version A35 also, compiled the
kernel with smp without smp. I have applied the most recent
patch, as you know len, and it currently does suspend properly
however, it does resume but X doesn't work.
Kernel 2.6.7 +
If anymore information would help let me know.
so with the latest kernel and a recent X sub-system, we're down
to video restore on resume?
Please try out the acpi_sleep options from Documentation/power/video.txt
Also, please try out the workaround in bug 3670
I tried passing the following parameters to the kernel
I had the same result. The system suspends just fine. However, when I go to
resume the system reboots. I have tried this running in X and in console mode
with the same result.
I am currently running the following:
Let me know if anyone needs more information.
the second parameter is
sorry for the mistake.
I decided to do some more testing on the kernel to make sure I could still
access the machine. I was able to ssh to the machine after I suspend and resume.
