Bug#711901: random xserver deadlocks in evdev
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
