Can you try to run "echo mem > /sys/power/state" instead of s2ram and see
if the symptoms are the same?

Also, please try reverting commit 7c0ea45be4f114d85ee35caeead8e1660699c46f
(reproduced below for conveninence) and see if that helps.

    ACPI: Ignore _BQC object when registering backlight device
    
    According to acpi spec , the objects of  _BCL and _BCM are required if
    integrated LCD is present and supports brightness level .The _BQC is
    the optional object. So the _BQC object is ignored when the backlight device
    is registered in ACPI video driver.

Hello Rafael,

I tested with that patch and the problem persists, when the laptop resumes it 
locks up (with a black screen). If I add acpi_apic_instance=2 acpi_osi=Linux 
as kernel boot options (as suggested by my dmesg) when it resumes I get back 
to a virtual term but I'm not able to log in. After entering my username it 
just hangs there.

Can you please test if the 2.6.24.4 kernel works, then?

What a coincidence, I upgraded to kernel-2.6.24.4-64.fc8 this afternoon. 
Suspend and hibernate work perfectly, even my wifi led works ;)

Could it be an error I made while configuring the 2.6.25rc8 kernel? Or maybe 
some other software that needs to be upgraded?

Most probably, there's a regression in the kernel.

Since the issue seems to be 100% reproducible for you, could you please carry
out a bisection to find the commit that broke things for you?

Hello,

I've never done a bisection before, I found this[1] page that seems to explain 
the procedure. At the moment I don't have too much free time to try that out, 
I can get back to you at the end of the week.

Thanks,

Have you tried if doing "echo mem > /sys/power/state" instead of s2ram works?

If you have, what graphics adapter is there in your machine?

Yes, I've been using /sys/power/state to put the machine to sleep ever since 
you told me.

Hm, Intel.  Do you use the i915 driver?

Well, I think that what you see is another form of
http://bugzilla.kernel.org/show_bug.cgi?id=10319
so you can add yourself to the CC list in there.

Good news! I was reading through the linux-kernel archives and I found this[1] 
post. It suggested using 2.6.25rc8-git2, I installed git4 and suspend works!

Thanks for your time, if you need anything else just ask.
