NVIDIA Quadro NVS 135M - I/O Journal error

[blwegrzyn]

I installed the latest nvidia drivers.
My system is dell latitude d630, NVIDIA Quadro NVS 135M.
When I try to hibernate, I receive an error:
journal commit io error
and I cannot do anything, system looses option to write to the harddrive and
I must reboot. Also if I use a system for some time same thing happens.

I was able to figure out that above is because of nvidia drivers,
after removing the driver from xorg.conf I can hibernate and computer does not hang,

Any ideas why nvidia driver could be doing it?

thx
