Output of lspci -vv
Description of problem:
If the system is hibernated and then thawed, we come to the gnome-screensaver screen is required. After punching in the password, the system keeps flickering the VT1 screen on every move of the mouse. Other screens are OK (using CTRL-ALT-Fx sequence), but one cannot login. Compiz was in use on this system. This happens with both tiling enabled and disabled. When boot option nomodeset is passed, the system works fine.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot into Gnome (compiz).
3. Thaw, type the password to unlock and observe.
This is a Dell Inspiron 6400.

Sorry - I had a nonsense moment :-( Ignore the last few words...
Is this a regression from the previous fc11 kernel? Or has it been like this for a while?
Can you try it with 142 and see if it works with that? You can get it from Koji:
Not sure if this is a regression. I just upgraded this box to Rawhide (a.k.a. F-11).
I'll try 142 and let you know, but other folks already reported that it didn't work for them on ATI hardware. Not sure if that's related or not.
142 is marginally better, but the system is still unusable. I can type in the password and there is not screen flickering, but I get this on the console:
init: segfault at 1 ip 08059c10 sp <various_hex> error 6 in init[8048000+20000]
This is accompanied by beeps at regular intervals (about 5 seconds). System is screwed - login doesn't work on other VTs, programs segfault immediately when run etc.
I'll attach my messages file. There should be more interesting stuff in there.

Oh, and disk is going berserk when all this starts happening. Not exactly sure why...
Anything in -152 that is related to this?
No dice - 152 is still causing all programs to die. I do get the desktop and I can click on the menu items, but nothing runs. I also cannot login to any other VT.
Kernel -155 gives blank screen on thaw. Changing VTs is not possible (still blank screen).
Can't reproduce this on x86_64 with any kernel I have installed (-140 to latest) on 965GM...
Both machines in question are not 64-bit capable. Kernel is i686 PAE kernel.
In that case, can you try with the i586 kernel?
OK, shall do.
BTW, is there something in -159 that may improve this?
No, not likely, but it's worth a shot.
Yeah, i586 kernel works. I tried with -155. So, definitely an i686 PAE thing.

Screen shot of the crash on thaw
-167 kernel is a lot better. I was able to hibernate/thaw once and get a fully functional system. However, when I attempted to do it the second time, I got the attached screen on thaw and completely frozen system.
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.
More information and reason for this action is here:
This still happens with 126.96.36.199-211.fc11.i586. I have an Inspiron 1505 1GB BCM4311 which is the same as a 6400.
Sometimes the first hibernate/thaw cycle works, but never been able to get more than one cycle.

Were there some .31 kernel fixes in this area? Anything that can get backported?
You could try booting a .31 kernel and see. I've seen a report in another bug that you can boot the latest Rawhide .31 kernel on F11 and it'll work.
(don't do this if you're using btrfs, but if you're using btrfs you deserve all you get :>)

OK, that sounds reasonable. I don't have btrfs, so it should be all good.
Nah, that didn't work. Can't even get X to start:

Fatal server error:

I'm guessing I have to wait until that gets fixed up.
yeah...maybe there's kernel-side changes in 2.6.31 that need a changed driver too.

Try kernel-2.6.31-0.81.rc3.git4.fc12.i686 and kernel-firmware-2.6.31-0.81.rc3.git4.fc12.noarch
I tested from run level 3 and successfully hibernated and resumed 5 times, without any segfaults. I rebooted to RL 5 and X and compiz both work and I've hibernated and resumed 3 times already. So this may be better.
Now I'm going to see how well I do with cpuspeed running and the acpi_cpufreq module loaded across the hibernate/resume cycle. If that goes OK, I'm going to try re-enabling exec shield, and reinstalling prelink, not that I think that will be a problem.
Today's kernel build from Koji hadn't finished when I tried this, so that one may work, but YMMV.
There may be hope yet.
Thanks for the tip Andrew.
188.8.131.52-32.fc11 is still no good. Flickering screen on thaw. Cannot login when I switch to another console.
Kernel kernel-PAE-184.108.40.206-64.fc11.i686 is a lot better than anything before. I was able to do this:
When attempted another thaw at that point, X hung (i.e. no prompt to login) and there were beeps coming from the system. I could not switch to a text console. Logs didn't reveal anything unusual - the system just hung.
So, closer, but not quite there.
Just bumped up one of the machines to F-12 and although there is no panic, on second thaw programs start crashing (segfaults in things like egrep, for instance). Hibernation is impossible at that point. Kernel is 220.127.116.11-127.fc12.
Almost there again...
I opened bug #537494, which is more or less this same thing for F-12 (with slightly different symptoms).
This message is a reminder that Fedora 11 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 11. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '11'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 11's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 11 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
