dmesg output - first bootup
I am running Debian wheezy and I have found that, with the nouveau driver
loaded, suspend/resume results in a hung system. Originally, I was using the
proprietary NVidia driver and suspend/resume worked with it. However, I
switched to the Nouveau driver after I found that the system was unstable with
the NVidia driver while watching videos. I have made sure that all traces of
the NVidia driver have been removed before reproducing the bug. Except for
this problem, the Nouveau driver works well -- no more crashes while watching
videos.
I have also confirmed that suspend/resume works after I unload the nouveau
driver. I use the following commands:
echo 0 > /sys/class/vtconsole/vtcon1/bind
rmmod nouveau
pm-suspend
I have also done a test of suspend/resume with Nouveau loaded after activating
pm_trace (i.e. echo 1 > /sys/power/pm_trace). I attach a couple of "dmesg"
outputs. The most interesting lines from the second "dmesg" command from
rebooting after the crash are the following:
[ 0.726626] PM: Hibernation image not present or could not be loaded.
[ 0.726635] registered taskstats version 1
[ 0.727033] Magic number: 0:56:725

Complete "dmesg" output attached.</pre>
