[ATrpms-devel] Problems with nVidia driver in FC6

[Tako Schotanus]

Hi,

unfortunately this is not the "easy" problem that John was having with 
the mismatched kernel arch because on my system the driver actually 
segfaults during boot with the message you can find at the end of this 
mail.

I also tried the kernel module from livna with the exact same result.

The problem I'm having is bigger than just the nVidia driver because I 
can't get vesa or nv to work on FC6 either! (and no, the system has not 
changed before wiping FC5 and installing FC6).

I've filed a bugreport with redhat with all the relevant info (xorg 
conf, xorg logs, dmesg output etc): 
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=212432

Does anyone have any idea what this could be?

BTW, are kernel modules somehow checked even though there are not loaded 
yet? I was mystified that this error appeared even though I turned of 
the graphical boot (removed "rhgb" from kernel options in grub) and was 
entering into single user mode.

Cheers,
 -Tako
