This is interseting to me because (as per previous emial) I
have tried *without* the script, and it seems stable to me with that
too!

root@dilbert:/home/petefrench # x86info -a | grep Microcode
Microcode patch level: 0x8001137

So, I am running a slightly later microcode than you are - want to give
that a try without the atch maybe ? Though I see its going into the kernel
which makes me very happy, as I prefer stability over pretty much anything
else on my machines :-)
