Hi,
I have problem with “kernel timeout” under Fedora 16.
I know, that it can be caused, by X server timeout, but in this machine I have some ‘normal’ graphic card and nVidia Tesla C2075
I think that Tesla is not even capable to run graphics interface. So why I have kernel timeout?

Is problem caused by fact, that in xorg.conf I have provided “nvidia” driver?
With this old xorg.conf X server didn’t want to start (“no screens detected”)
