This sounds a lot like bug #376092, which I'm about to upload the patch
for, along with the patch for bug #360319 (another memory leak). I'm
going to dupe this to #376092. (Both of these are actually bugs

Sorry to double-post but just realised I lied. :-)
Since the bug was filed against 2.6.28-11 and we've gone around it by
going to .30... what we gonna do about a fix for official Jaunty?

Been looking through changelogs for the version Bob Manners and I have
been going through... I can see there are several memory leaks that
might have been the culprit that have been fixed recently, or that had
been fixed in drivers way in advance of what I was running.
Bob: your bug, but suggest
Hi there - just a quick update.
I have been running with 2.6.30 for a couple of days now, with a
relatively light workload under KDE4. My overall impression is that
this problem has either been fixed or that the leak which is probably
the root cause of this is at least much slower now!
After
I am also confident that bug had gone after upgrading to kernel 2.6.30
and using intel video drivers (from x-swat ppa) that default to older
acceleration architecture (EXA).

I don't know if this is specifically an intel bug. I sometimes see the
same thing occur and I'm using nvidia.
It happened again just now: the PC was doing nothing all night, but when
I returned to it and pressed a key to stop the screensaver, X had become
unresponsive due to disk thrashing. I
There were lots of changes to this area of DRM in 2.6.30rc7 and rc8 -
could be worth trying this kernel and seeing if the problem goes away?
If it does I don't think it will be too hard to identify the exact
changes which fixed it...

I also experience the same bug on notebook with i945 chipset with Ubuntu Jaunty.
Symptoms are the same - at some point system becomes irresponsive, disk
activity is such high that the only option is to power-off the notebook.
As I was experiencing it rather frequently I had open consoles with
I'm confirming this. My restart X cycle happens at approximately once every 5
or 6 hours of usage. The symptoms are exactly as mentioned, but with an
addition. /proc/dri/0/gem_objects shows a large number of GEM objects
allocated, but the number of GEM objects does not really matter. What

I am not at all sure this is a kernel bug, but I don't know what else to
file it against. Perhaps someone who understands the VM subsystem could
look at my logs and provide some indication of what may be the culprit
here.

I can confirm this behaviour on both my laptop and my work PC.
My PC has 2GB RAM and I have configured a 4GB swap partition. With KDE 4.2,
compositing turned off and only a firefox tab htop says 2.7GB of swap are used.
That cannot be normal. My RAM is only at 450MB (excluding cached memory).
In my case restarting the X.org server clears the swap.

Further Followup - Behaviour with Swap Enabled
-
After posting this bug, I created swap partition on a spare ~1GB disk
partition. (Who needs HP Quickplay anyway?)
The results were interesting ...
I noticed over the course of 48 hours
One more datapoint - system has been up 1 day almost exactly.
Sitting idle in KDE session with just Firefox running:
htop gives 621MB used of 2004MB physical
Swap sits at 540 / 1027MB used
top gives me:
top - 19:38:12 up 1 day, 34 min, 1 user, load average: 0.90, 0.50, 0.47
Tasks: 173 total,
This sounds like a kernel issue and therefore should be against linux
rather than -meta. Moving to the appropriate package.
