A breakthrough in this thread has happened. 

I ended up taking a backup of the disk to an external hdd using

> # dd if=/dev/sda of=/mnt/angrist-sda-18nov14.img

then I booted FreeBSD 10.1 memstick, entered shell and entered some commands:

Then I rebooted into ArchLinux iso memstick to install Arch on the 20G
partition and using the other one as /home. So now Syslinux works,
unfortunately I don't know why. And I was able to install all new packages
including linux 3.17.3-1 and intel-ucode 20140913-1, loading it in Syslinux
according to the wiki.

I got a new mce after exactly three hours:

I am also making this output an attachment. There is a lot of more
information in this new mce compared to the other one I sent.

Perhaps some of you got some new suggestions.

Meanwhile, I am downgrading back to 3.11.5-1.
