<pre>It seems that the BIOS upgrade did have some impact on the behavior. Now when I
boot using linux 3.8 or 3.9, the screen either randomly shows scrambled lines
as before or starts X as normal and the CPU hangs after I log in. because of
the random behavior, it has been difficult to bisect the code which lead to
this problem.
I am attaching a file which contains the dmesg logs showing the CPU hard lockup
error.</pre>
