dmesg from failing machine
Plugging in an VGA monitor and trying to enable it results in black screen on
both the internal laptop display as well as the external VGA monitor.
The graphics is dead after this, I have not found any way to restore the
screen. However the machine is still responding to ssh and I was able to pick
up an quite interesting dmesg snapshot.
If you need me to test patches or need any other information, just ping me.</pre>
