Package: xserver-xorg-input-evdev
Version: 1:2.7.1-1

Xorg randomly hangs about once per day.

As far as I remember  the problem  occurred when I had the stupid idea to install
gnome-shell 3.8, which, I think, also pulled in a xorg update.

I am using Debian GNU/Linux amd64 unstable + xorg and gnome from experimental
(so I get what I deserve) with a custom kernel 3.8.13 (gcc version 4.7.3 (Debian 4.7.3-4) ),
libc6 2.17-4 on a macbook pro 4,1.

When the Xserver deadlocks it is still possible to ssh into the machine. It also was
possible to attach gdb and force a return from _int_free( ... ) and continue to work. 

Backtraces with limited information) are attached in the hope that they are useful.

The macbook pro has a hardware problem which causes the usb touchpad to disconnect 
from time to time due to a bad electrical connection. Not sure whether this problem 
is related to the xserver deadlock. This hardware problem seems to be a general
problem for these models and is transparently handled under MacOS X. Such a problem
happened about at the times when I experienced this problem.

With many regards,
  Götz Gaycken

That change was included in 2.8.0, so marking as fixed in that version,
thanks.
