kernel 2.6.16.14 & nvidia - strange problem

[Haris Peco]

Hello,

   I have compiled kernel 2.6.16.14 (pure kernel with some patches out of ubuntu kernel compilation) and
add latest nvidia driver (manual from  NVIDIA-Linux-x86-1.0-8762-pkg1.run)
  It work fine, but when i restart machine some programs throw 'Segmentation fault' - for example openoffice
When i reinstall NVIDIA drive it work again until next restart

What is my problem ?

Thanks
Peco
