Description of problem:

After PXE booting a test machine using F13 images from 2010/04/27 the moment anaconda starts a graphics server the first screen does show up but both a mouse or a keybord fail to have any effects.  That means that I cannot get to any logs from that boot as an external access is also non-functional.

I cannot exclude that X is crashing in some nasty manner but effects are always the same regardless if I am trying to use some options like "nomodeset" and/or "xdriver=vesa" and whatever else I am trying.  OTOH anaconda apparently is loosing track of input devices (cf. bug 586607) so maybe the same happens with input devices?

Version-Release number of selected component (if applicable):
anaconda version 13.38 on x86_64

How reproducible:
every time

Additional info:
Hardware information about a test machine can be found in logs attached to bug 586607.  This machine runs currently various Linux installation, which include Fedora 11, Fedora 12 and the current Fedora rawhide, and none of these shows symptoms like those in anaconda.
