Description of problem:
After issuing either "echo mem > /sys/power/state" or
"echo 3 > /proc/acpi/sleep" apparently the machine goes
to sleep (the disk stops, the monitor goes off, the cpu
fan stops, the power indicator starts blinking, etc).
Next I try to ressurect it by pushing the power button.
From what i can tell it tries to resume (the disk starts,
the cpu fan starts, the power indicator stops blinking)
but it fails to complete - the monitor is still off and
the machine seems pretty much dead and needs to be powered
off and started again.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. echo mem > /sys/power/state
Actual Results: The laptop fails to resume when suspended to ram.
Expected Results: The laptop should resume.

JFYI, resuming from "echo standby > /sys/power/state" works just fine.
Can you try the 383 kernel from http://people.redhat.com/arjanv/2.6
it has some suspend/resume enhancements....
I've downloaded and installed kernel-2.6.6-1.383.i686.rpm .It behaves
identically as much as I can see. The system still cannot fully restore
from Suspend-to-RAM (in particulary the screen remains blank and the
system is non-controlable, but the network TCP/IP stack responds
to ping request send over the network).
Any further hints on how to proceed ? I'd be happy to help tracking
Keep tracking the kernels on that URL, I'm working on suspend stuff in
It's not quite all there yet but it's one small step at a time :(
I have a similar problem on a Dell Inspiron 4150 laptop. To test this,
I switch to a console display. Under ACPI, suspend to mem, and then
resume leaves me with a blank display. I am able to reboot using
Ctrl-Alt-Del (which seems to be an improvement that appeared with the
new test kernels).
Switching displays using Ctrl-Alt-F7 lights up the display which
appears all white with some black vertical lines. Switching back to
console with Ctrl-Alt-F1 again leaves me with a garbled display.
I have a Radeon Mobility M7 graphics card (similar to Comment #2, but
Suspend to RAM works fine under APM.
Still no good with -422 .. will continue to test more kernels as they
any improvement in the 2.6.9 errata kernels ?
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat. The Fedora legacy project will be producing further kernel
updates for security problems only.
If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.
