dmesg with loggingv2 patch applied
Here is the dmesg from another system, with the same (G73, NV40) video adapter,
with two smaller monitors (1240x1024).
Notice that there are a lot of CACHE ERROR message. So many that the printk
buffer overflowed.

BTW The user of this system is not doing much with it, so the logging is
preliminary. I'm waiting for more details to show up. In the mean time, this is
what we get after the first login.</pre>
