Description of problem:
After entering suspend to memory with:
echo "mem" > /sys/power/state
which works OK, the notebook won't come back properly. The power comes
on but the screen remains blank. CAPS LOCK and NUM LOCK change states
fo LEDs but the keyboard does nothing else.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Enter suspend to memory.
2. Try to power back up.
I'll attach files as per bug 121020.

Please retest with kernel-2.6.5-1.358 or newer. There have been
several major fixes that may have improved this situation for you. If
it fails, please retest with the same version but i586 kernel.
Nope. Same deal with 358 i686. Let me try the i586...
With i586 keyboard doesn't even respond to CAPS LOCK, NUM LOCK etc.
The lights come on (i.e. various LEDs like power button LED etc.), I
can even hear the CPU fan going after a while, but the machine is
otherwise dead. Hope this helps.
Do you need any other info about the machine's hardware?
BTW, even when I do the suspend to memory from run level 1, it does
the same thing (i.e. running X doesn't seem to be the cause of this
issue). Suspend to disk does nothing at all.
If it's of any help, the vanilla 2.6.6 does more or less the same
thing with suspend to memory. The machine goes into suspend, but when
it comes back, it is dead although the LEDs come on. No keys on the
keyboard do anything.
The main difference that I can see is that "echo disk >
/sys/power/state" in fact _does_ write something out to the swap
partition. I'm still unclear how to get that back (the resume=/dev/xxx
doesn't seem to work), but hey, it's better than nothing :-)
Suspend-to-disk is not compiled in FC kernels for some reason. Neither
the new (/sys/power) nor the old method (/proc/acpi). I was wondering
if this issue qualifies for bugzilla entry but I guess the maintainers
had something in mind.
suspend to disk is quite really badly broken unfortinalty.
Ok new kernel uploaded to http://people.redhat.com/arjanv/2.6
it works better for my machine, but I do have to unload the ehci_hcd
module before i can suspend for some reason (still investigating that)
Just FYI, kernel-2.6.6-1.435 is still a no go on this notebook.
Kernel 2.6.8-1.521 still doesn't do this right.
Still the case with FC3T2, kernel 2.6.8-1.603.
Please do not expect us to investigate your issue. You must push
upstream kernel.org and use bugzilla.kernel.org. If they manage to
fix this, then the FC kernel will have it when we upgrade to the
latest upstream kernel.
I was just reporting this so that we have a full history of it. But,
if you don't wan't me to do that, I can stop.
Reporting is fine, so others see this report. But if you want a
solution, bugzilla.kernel.org and the upstream ACPI project is where
you must seek help.
No worries. Shall open one today and post a link to it here.

suspend2 works fine, so I'll close this. It seems video related anyway - radeon
driver needs to soft boot the cards or something like that.
