Blank screen/machine hang with two video cards, one in use
 
When debugging this problem:
http://www.nvnews.net/vbulletin/showthread.php?t=152235

I also had another one: the above configuration, which works fine both for new and old Xorg releases and both for x86_64-256.35 and x86_64-195.36.24-pkg2, will hang the machine when an unused video card is present.

I have a GTK275 in the lowest PCIe slot. When a 7300 is also present, in an upper slot, then starting X11 with either of those drivers will lead to a blank screen, no reaction to keyboard presses and no network reactions. In a word, a hang. The keyboard LEDs are not blinking which would mean it is not a panic but it is also possible that the kernel tries to blink them and X11 has hijacked them already. Removing the 7300 fixes the problem. Xorg -keeptty showed the same behavior, same blank screen, no LED activity.

Xorg.log and config file from when only one card is present are here (same as other thread).

I only have an Xorg.log with both cards when I run Xorg-7.1.1. Apparently that worked better than the new Xorg. The problem is somewhat intermittent, although the new Xorg reliably did this every time today.

Just bumping this. The machine in question isn't supposed to be crashed so I can't go debug it more and plan to drop the issue. Unless somebody else sees this and needs it?
