I can duplicate my problem everything, and I can make it stop a will.

doing "dd if=/dev/sda of=/dev/null bs=64k &"

and then

        "dd if=/dev/sdb of=/dev/null bs=64k &"

will cause the problem within a couple of seconds.

Doing "kill %1 %2" (assuming the dd's are %1 and %2) will
stop the machine from hanging on disk io within 30-60 seconds.

Once it hangs it does not appear to do any disk io until the
offending processes are killed.
