Yes, been through the majority of items including irq's, swapped
motherboards, ide only, nothing else running, command line only (no
frame buffers), upgrade from rhv9 to fedora 3, mucked with pci
latency, etc.  Had not tried the hyperthread thing until now, but 
that had no effect either. Even upgraded the TDM card to the latest 
rev h.

Still think its either a bad TDM card design, or, TDM driver issue
as to why we can't approach zttest results of 100%.

I'm hoping that Steve Underwood's utility to measure the TDM results
helps to identify the root cause.
