Description of Problem: If you switch the VT terminal when firstboot is running, firstboot can exit without warning. Duplicated this problem twice also on the GX100 this morning. Video card is a i810. The way to duplicate the problem is to do the firstboot, in the RHN registration section, remove the wire or something to cause it to not be able to connect to the servers. while it is waiting to timeout, switch to VT-1. pop, firstboot exits and we are switched back to VT-7 as gdm startsup.
I have not been able to reproduce this, but the only i810 box I had died about three months ago. I will have to scrounge one up and test. Other people have reported some similar (but not identical) problems with i810 boards.
From an email with mike harris this is a bug with the i810 kernel module not having the capability to switch the 'permissions' of the console. This bug shows up when switching from a logged in XFree86 session to a virtual console so is not just firstboot bug. Closing since it is a kernel/XFree86 problem.
