Comment 5 for bug 66900

I have attached the dmesg log captured soon after a bootup.
I am using a fixed DSDT for the Ferrari 4005 (which I fixed myself).

[NOTE: While looking over the log file it eventually filled up the dmesg buffer, but I noticed the "many lost ticks" warning at the end]

A quick analysis shows these interesting entries:
