comment How do I convert a RAID 4 array to RAID 0?
I happen to have a test box here, and am trying to replicate. Unfortunately, I can't add a disk to the array in the same way you did: "mdadm: add new device failed for /dev/sdf as 3: Invalid argument" - so I think there's something to how you originally created the array that led to it adding the disk as a parity disk.

comment TAB key stopped working
I don't know the cause, but have seen on rare occasion a key get "stuck" or otherwise non-responsive, only to be fixed by reboot or power-cycle. Maybe it was remapped by another program?

Does the problem persist past reboots?

comment Ubuntu 14.04 fails to boot - libpcre.so.3
Doesn't anybody else thing it's odd that @Swifty is getting the same error on libpcre... for everything? /sbin/ldconfig is statically linked, so there should be no problems running it. I would be very wary of the system, as if some broken rootkit which needs the library to perform a lookup before a command is causing that warning. May be a good time to reinstall.

comment Kill 2 other process with .sh Script
Is the process definitely killed? Try "ps -ef | grep rtl_f[m]" and see if anything is listed. If it is, then yes, the process was not killed. If it is not, then process was indeed killed, but there is a device driver problem leaving the rtl device inaccessable. I have seen this happen before, although on other platforms. My only resolution then was to unplug the RTL dongle and plug it back in again.

comment Unable to install ubuntu desktop
If after all of this the problem persists, I think it's a motherboard issue. If your machine is new enough and still under warranty, you should contact them. I doubt a warranty replacement would solve the problem, but it's worth a try. Otherwise, if it still fails with a new machine, I would demand that they give you credit to exchange for a different model. This is a very rare condition, so don't get discouraged! Ubuntu is great.

I also found a few others with server hardware giving them problems. They recommend disabling C-States in the BIOS, which may be called something else, but is related to power-saving modes of the CPU itself. You can read more about this and other possible kernel boot options at bugzilla.redhat.com/show_bug.cgi?id=548198
