Regression: Compiz is not responding on fedora 12, kernel-PAE-2.6.32.10-90.fc12.i686

I had fedora 12 installed on a Macbook pro Intel first generation with ATI Radeon graphics card (see the attachment).
Compiz crash when trying to watch *.wmv movie codified with wmvvc1dmo on kernel-PAE-2.6.32.9-67.fc12.i686.
I want to convert the film to *.mpg, then I download the mplayer codecs in order to see the film, I can do it without problems with the on kernel-PAE-2.6.31.12-174.2.22.fc12.i686. But I updated my system last Saturday and when I was trying to see the movie again the computer began to respond really slow, then I began to close applications and when I tried to restart I got the message: "compiz is not responding". I tried again but the same problem. Other thing that I noticed is that when the computer go to sleep, when I wake up it, the display show horizontal black spikes, it is like it doesn't have the appropriate refreshing rate.
I think that the problem is related with the acceleration on graphic card.

Yesterday, I booted on kernel-PAE-2.6.31.12-174.2.22.fc12.i686, and I watched the film, and the wake up was without problems. That is the reason I call it a regression.

How reproducible:
Every time when you boot with the this kernel


Steps to Reproduce:
1. Boot on kernel-PAE-2.6.32.9-70.fc12.i686
2. Open a *.wmv movie codified with wmvvc1dmo with mplayer
3. Wait a little and the computer will begin to fail

Question Re: Regression: Compiz is not responding on fedora 12, kernel-PAE-2.6.32.9-70.fc12.i6

The same happens with the new kernel (kernel-PAE-2.6.32.9-70.fc12.i686).
Then if fedora people cannot fix the problem, I need a way to stop the kernel updating.
Ideas welcome thanks in advance!

---------- Post added at 10:54 AM CST ---------- Previous post was at 12:29 AM CST ----------

Maybe my problem is particular to my system. I have disabled the updates in my preferences, but I hope that this bug is going to be fixed in incoming kernels. Then I have a question:

As I have seen, fedora keeps 3 kernels, when a new version appears and you update the lower version kernel is erased. Now I am using this lower version and I don't want it to be erased because my system is fully functional, at the same time I would like to try the incoming kernels in order to see if the bug is fixed.

I am using kernel-PAE-2.6.31.12-174.2.22.fc12.i686, and I have also kernel-PAE-2.6.32.9-67.fc12.i686 and kernel-PAE-2.6.32.9-70.fc12.i686, if a new kernel appears and I do the update then:
Will I get erased kernel-PAE-2.6.32.9-67.fc12.i686? Is there a way to do that?

Thanks in advance.

Correct.

No: the lowest kernel version-release is erased.

You can either:
  • Exclude any further kernel[-PAE]* updates globally by appending the following line to /etc/yum.conf:
    exclude=kernel*
  • Increase the maximum number of installed kernels allowed by changing (in same config file):
    installonly_limit=5
    Or whatever number you want; NOTE: YOU MUST HAVE SUFFICIENT HDD SPACE ON /boot/ partition to install these extra kernel packages - each kernel consumes ~25 MB, plus you need a buffer at least that same size (and preferably: more is better).
  • Erase one or more of those non-functioning kernels to create HDD space and/or open a slot in the 'installonly_limit' queue. For example:
    su
    yum remove kernel-PAE-2.6.32.9-67.fc12.i686 kernel-PAE-2.6.32.9-70.fc12.i686
would leave only the one (working) kernel-PAE-2.6.31.12-174.2.22.fc12.i686 (and two "slots" in the 'installonly_limit' queue, assuming the default of 3). NOTE that you must always leave at least one kernel, or you cannot boot.

Re: Regression: Compiz is not responding on fedora 12, kernel-PAE-2.6.32.9-67.fc12.i6

Thanks for answering! I think the better option is to erase the two kernels that don't work for me. Then I will enable the updates, but I am wondering if I will have problems with the other packages.
I mean, Is there a possibility that if I update a package, it wouldn't work with the old kernel (kernel-PAE-2.6.31.12-174.2.22.fc12.i686)?

Packages that won't work with older kernels should be built with a dependency that says what minimum kernel version they require. So if you don't get a dependency error, it should work.

Again the new kernel is failing (kernel-PAE-2.6.32.10-90.fc12.i686). Same problem

I am wondering if I have to keep this kernel and fedora version all the time. I want my machine being fully functional. I don't know what I will do when fedora 13 arrives.

Puff, It is a pity that you cannot trust in fedora for lap-tops.

Re: Regression: Compiz is not responding on fedora 12, kernel-PAE-2.6.32.9-67.fc12.i6

Not sure if this is related
With fedora 2.6.32.12-115.fc12.i686 and fedora 2.6.32.11-99.fc12.i686 running with gnome
I get extremely slow window response (for example if I click Preferences I have to wait for 10 to 15 secs before the menu appears).
When I log out a window opens saying
"A program is still running. Compiz is not responding"

But there is no such problem with Fedora 2.6.32.10-90.fc12.i686 running with gnome
and neither is there any such problem with all three fedora versions running with kde.
