Hi,

I think I am hit by the same bug in stable 3.7.1. My box has the same behavior,
it effectively freezes completely and can only be hard reset and boot back into
a different kernel version. 

I managed to track down that the problem does not occur on 3.6.10 or 3.6.11.

I looked at my logs, but there is nothing in the 3.7.1 log, as the system locks
up before managing to write anything on disk or on screen. It does seem to lock
up when it attempts to modeset though, as it freezes inbetween the kernel boot
sequence. I do see some errors in the 3.6.10 log, but I don't think they are
relevant:

this is a headless server system that I very infrequently use the console or X
directly on. I tried passing the kernel parameter "nomodeset", which apparently
boots me into 3.7.1 without a problem (only the console resolution is odd). It
would be great if it can be fixed.


The system is based on a Commell LV-67AD2 Mini-ITX board (
http://www.commell.com.tw/Product/SBC/LV-67A.HTM )

CPU : Intel(R) Core(TM)2 Quad CPU    Q9400  @ 2.66GHz
memory : 4GB
Distribution : Gentoo x64

Let me know if there is anything to test.

thanks,
stathis
