[Bug 28902] New: activated KMS leads to complete freeze when viewing BIG images in Iceweasel

           Summary: activated KMS leads to complete freeze when viewing
                    BIG images in Iceweasel
           Product: Drivers
           Version: 2.5
    Kernel Version: 2.6.32-5-686
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
        AssignedTo: drivers_video-dri@kernel-bugs.osdl.org
        ReportedBy: spamfang1199@yahoo.de
        Regression: No


In early versions of 2.6.32 line, my system used to often freeze when I tried
to open big (1,7mb+) images in Iceweasel. Since the kernel got updated, these
freezes seem to have vanished.

But now I can reproduce the freeze every time, when visiting a certain .onion
site and there viewing a certain picture. Therefore I uploaded this very
picture to another pic-hoster and tried to view it there: The machine did NOT
freeze. So it is not the fault of the picture itself. It is the teamwork of
that specific .onion site and that picture.

This bug occurs NOT, if I deactivate KMS.

When the system is frozen, i can ping it, but not SSH into it any more.
Backtraces are very seldom. I only got 4 (see attachment) since the logs
usually show nothing.

I have to add another thing: 

With activated KMS the desktop always freezes for a few seconds, when opening
large pictures in Iceweasel, or clicking on the tab which contains this large
picture. It also shows this behaviour, when switching between windows. In
earlier versions of 2.6.32 the system often used to freeze completely at that
moment. Now its only for a few seconds, except I try the mentioned .onion site
with that certain picture.

Can you try with a newer kernel?  2.6.37 or 2.6.38-rc?

I will try as soon as a newer kernel will be available in Debians SID or
Experimental tree.

2.6.37 has been in the experimental tree for over a month.

Sorry, but 2.6.37 is not in experimental, only a meta-package. Therefore i
compiled my first own kernel. But it wont work well with my radeon card. I was
able to log into KDE only once. From there i tried to switch users, which froze
my system completely. After a hard reset the machine froze right after booting,
while trying to bring up KDM-greeter. I tried several times. All with the same
result.

I am using a radeon 9600 with the free radeon driver.

Perhaps i did something wrong during my first compilation steps. I just list
the steps, i did:

tar xjf linux-2.6.37.tar.bz2
ln -sf linux-2.6.37 linux
cp /boot/config-2.6.32-5-686 /win/linux/config
cd linux
make-kpkg clean
no '' | make oldconfig
fakeroot make-kpkg --initrd --revision=custom.1.0 kernel_image
dpkg -i linux-image-2.6.37_custom.1.0_i386.deb

Here i add some logs from 2 different crashes with 2.6.37. I archived them
right after the crash by rebooting into runlevel 1, so that X was not started.

Closing as obsolete, if this is still seen on modern kernels please update
