Re: X server 1.9.3 crash on Fedora 14, GeForce 8600 GTS
I think I found a solution to this. Well at least I was not able to reproduce it anymore.
This issue is somehow related to PCIe power management/saving stuff on the kernel.
So adding "pcie_aspm=off" to your kernel line in grub.conf fixes the issue!!! I upgraded to the newest 270.18 nvidia driver as well as to the latest xorg-server supplied by Fedora 14 and was unable to get a xorg freeze.
Please try this out and let us know, if it works mark the post as solved.
