Kernel GEM tiling Oops, after a couple hours the system starts swapping and X locks up.

output of /proc/meminfo minutes before lock up.
Description of problem:
I am running Compiz on my Inspiron 1420n with X3100 intel graphics. Nothing special. 2GB of RAM.
I have no xorg.conf or anything like that. This is a fairly new install of Fedora 11 beta from your guy's iso images.
What happens is this:
I am running this with a Gnome desktop. Uses about 512MB idling. Then on top of that I am running a Debian VM in KVM (via virt-manager) and all that with it allocated 512MB of RAM. Typically with this setup I should have somewere between 300-700 megs just there for cache and zero swap activity.
What happens is that I start getting slow responses from the system and nonsense coming from 'free' command. For example I just rebooted after doing a forced shutdown of my system after X locked up. Right now I have this from the 'free' command:
$ free -m
total used free shared buffers cached
Mem: 1982 874 1107 0 107 392
-/+ buffers/cache: 374 1607
Swap: 3903 0 3903
This is just a newly booted up Gnome + Compiz system. After starting up the VM I've been working on and running X for a while I start seeing odd values like:
-/+ buffers/cache: 481 1501
Swap: 3903 601 3302
and stuff like that. I had a swap used up that much just moments before X locked up. At most, with Fedora 10, in my worst/busiest days I may only end up with 32 or so of megs touched in swap. I very very rarely hit it, and yet now with Fedora 11 I hit it every single time. hit it hard.
I managed to grab a copy of /proc/meminfo a few minutes before I lost control of the machine. I attached it to this bug report.
Every boot up I get this message in my dmesg output. Every single time. sometimes multiple times:

I get no errors in Xorg.*.log* and I have no xorg.conf
I was able to recover once using ssh from a seperate machine and kill -9 Xorg... immediately after that the machine stopped swaping (swap went from 500+ to 12) and I was able to log into it again, no problem and continue using it. I only tried that once, I am on dhcp and it's hard to find my address so I usually just use the power button to force a shutdown.
This is about the 3rd time I've been trying to write this message before X locks up.
Thanks otherwise. This version of Fedora is very fast and I have no performance penatly that I can tell from running composited desktop anymore, besides this of course.
I am going to disable tiling in a new xorg.conf and see if I can make the problem go away. I just wanted to make sure to get this bug report out before I tried anything.
It swaps so hard that I can just sit there with 'watch free' running and see the swap getting used up, bit by bit, the system not doing anything otherwise. It's very bad.
Version-Release number of selected component (if applicable):
Oh, sorry. I forgot to mention that I am running Compiz this entire time. UXA, KMS, DRI2 and all that working as far as I can tell. I don't know this would happen without running Compiz, I am guessing that it would probably still happen, but it would take days to lock up instead of hours. just my guess.
Hrm. Running with:
Identifier "Builtin Default intel Device 0"
Option "Tiling" "0"
Identifier "Builtin Default intel Screen 0"
Identifier "Builtin Default Layout"
Screen "Builtin Default intel Screen 0"
As my xorg.conf file seems to solve the problem with X locking up. It was very stable.
However I was still swapping like crazy. By the time I had to shut down my laptop to go home I had 700+ MB written out to swap. But when I tried to figure out what the problem was I couldn't find it.
I tried stuff like this:
ps h -eo %mem|while read i ; do POO=`echo $i+$POO|bc`; echo $POO ; done
ps h -eo rss|while read i ; do POO=`echo $i+$POO|bc`; echo $POO ; done
then I was only showing about 55% memory usage.
So I have no clue what was going on.
But disabling tiling in xorg.conf did stop the oops
After doing a 'yum clean all' then a 'yum upgrade' then rebooting I am no longer experiencing oops, even with my xorg.conf removed and using all the defaults for X Windows which leaves tiling enabled.
However I am still hitting the swap.
After a few hours of using Gnome+Compiz for little more then a web browser, a gnome-terminal, and a emacs session I am using up a full 2GB of RAM and nearly 300MB of swap. No big compiles or VMs running or anything. Just a pretty much default desktop install of Gnome with compiz running.
However free -m still informs me that I have 1400MB free minus buffers/cache.
Once I killed X by running 'telinit 3' the amount of swap being used dropped down to 77MB and free -m says that I am only using 168MB of ram, which still seems excessive to me for running without any desktop.
I attached output from free and /proc/meminfo from before and after killing X. I have not ran into issues with X locking up yet. But last time I would have to be using 500-700MB of swap before X locked up.
I am now on kernel 18.104.22.168-54.fc11.x86_64

Output of free -m and /proc/meminfo before and after killing X
Just a update.
The issues with memory leaking are still continuing with the latest updates.
~$ uname -r
~$ rpm -qf /usr/lib64/xorg/modules/drivers/intel_drv.so
~$ rpm -qf /usr/lib64/dri/i965_dri.so
A couple times a day, while using compiz, the system will gradually use up more and more ram and start swapping, eventually locking up X. Not using Compiz will slow it down consirably, but it will still cause problems.
No more oops, like I mentioned above they were gone for quite a while, but now stuff like this is showing up in dmesg:

It repeats quite a bit:
~$ dmesg |grep Xorg|wc

~$ dmesg |grep blender|wc

I don't mind compiling custom kernels or patching things or anything like that. While I don't know which part of the equation is the problem I would be happy to do anything I can to help resolve this.
Or am I completely confused about what is going on? Should all of this be a different bug report or anything like that?

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 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.
