Default X freezes with glx applications

Hi, I just started having an issue with my glx applications (compiz, glxinfo, glxgears, the opengl/glx information tab in nvidia-settings) since updatign my computer. Every time I start one my X hard freezes. I can ssh into my system but X is unresponsive. X is taking up 100pct of the proc according to top, and I cannot kill it, I have to hard reset my comp. Also a note, it was several days after I updated my system before I rebooted and the issues started.

First I removed compiz and its other packages(I'm using gentoo) and then I checked over my Xorg.conf to make sure GLcore and dir were not enabled. I also disabled composite and rebooted.

Also I have tried older versions of nvidia drivers, seeing as my problem started after a world update. Finally I recompiled xorg-X11 and still nothing.

I have searched all over and found nothing but this:

http://gentoo-wiki.com/HOWTO_nVidia_...or_OpenGL_apps

which describes my problem exactly (I get the erronous messages by tailing /var/log/messages from ssh) but my NX/XD bit is off and I am not using hardened sources for my kernel. Also I can find nothing on these forums relating to this problem.

Code:
# tail /var/log/messages

I see exactly the same issue on a freshly updated Debian testing.
Each time an Open GL application is launched, the nvidia kernel module is oopsing badly in os_set_mlock_capability

I reverted to an older nvidia kernel/glx but it didn't change anything. I reverted xorg and it still doesn't help.
I'm wondering what I could revert now...
Oh, and this is on kernel 2.6.22.1 on which I added CFS...
It was working fine with the exact same kernel...
Any idea what could be wrong ?

Default Re: X freezes with glx applications

What version of nvidia drivers are you guys using? I'm having the same problem (my kernel oops looks almost exactly like masterzen's) with linux 2.6.23.9-1 and nividia-100.14.19. Has there been any improvement since October? (i'll post a proper bugreport when I get home from work)

[edit]
I uploaded a tar.bz2 file that includes the nvidia bug report and the dmesg that I captured of the kernel oops.
