dmesg with dc=0

This is booting with dc=0. Again, the command run was "DRI_PRIME=1 glxgears ||
dmesg > dmesg.dc0.post".

Interestingly, this time the computer did not crash and there is a message
about a gpu crash dump in there, which I unfortunately only saw after I
rebootet. I'll do it again to get that and then file a bug against DRI/Intel
here as suggested by dmesg.
