Well, it reeks of bad interaction of Linux and the firmware, which *usually*
is caused by bad firmware when an Intel desktop
says that disk bandwidth is much lower
than it should be, but only when hyperthreading is enabled. But, the
system doesn't appear to be THAT much more unresponsive when
hyperthreading is enabled over when disabled. So I'm leaning toward the

Hmm, there's a way to test. Time how much
if=somefile bs=10M count=100 ;
but I wasn't able to find a way to purge the disk cache before I got
sidetracked. Perhaps you know of a magic incantation for that?

I've attached the contents of /proc/cpuinfo below, two copies, one with

I've also investigated things a bit further and now I'm thinking that
the hyperthreading state affects the system as a whole, not just hdparm.
First, I've attached hdparm output
