Startx crash after update

[Fil-ShinyMetal]

Hi there,
I will describe shortly my situation.
2 Z800 HP server, 6 GBytes of ram with 1 80 GB sata for the os and 2 sata 1TB in software raid1.
The graphic board is an Nvidia Quadro FX380
I have other servers ( FC10 ) that mirrors locally the update and everything publicly available repositories.

The installation went smoothly with FC12_64.
After the installation I arranged to boot in text mode, no graphic ( I do this for all my servers, so nothing strange ).
I got the first troubles when I did the updates : doing a startx, both the Z800s rebooted, and unbelievably the discs were no more accessible : the only way to recover from that was to cycle the power !
Quick investigation, and I discovered that with the installation kernel ( 2.31.5 ) X starts well.
Googling around, I discovered the solutions proposed in the  http://fedoraproject.org/wiki/Bugs/Common but none of them worked for me.
I've not yet tried the Nvidia driver for time reasons, maybe tomorrow I will do, but I suspect the problem is not there.
As a last bit, I did the installation and update with 32bit FC12, with the same results.

Any idea about this?
Regards

Filippo
