RJARRRPCGP said: If you do a "pacman -S nvidia" and reboot, you will get:
ERROR: root fs cannot be detected. Try using the rootfstype= kernel parameter.
ERROR: Unable to create/detect root device '/dev/disk/by-uuid/xxxxx
Dropping to a recovery shell... type 'exit' to reboot

Thus, you will be stuck in a reformatting and reinstalling trap!
With this bug, you would be wondering if it should still be in alpha! :evil:
I don't think this has anything to do with nvidia drivers. I don't see how nvidia would affect recognition of filesystems by the boot image.
I also have two Arch machines that use nvidia drivers and I never had any problem like this.
In either case, this kind of problem is not something that requires either reformatting or reinstalling. Just make sure that the uuid identifiers are correct in menu.lst/fstab. Alternatively you can ditch uuids and use the old style /dev/sdX designations for filesystems.
See this for how to deal with kernel panics (which are usually easy to fix): http://wiki.archlinux.org/index.php/Kernel_panic First thing you should try when you boot into your system, aside from checking that grub and fstab configurations are OK, is regenerating boot images with "mkinitcpio -p kernel26".
