Also a note, it was several days after I updated my system before I rebooted and the issues started.
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 188.8.131.52 on which I added CFS...
It was working fine with the exact same kernel...
Any idea what could be wrong ?
