Well, I upgraded to the latest driver today and the problem persists.
(By the way, upgrading via the driver source does also upgrade the
firmware and BIOS.)  I spoke to 3Ware support.  They seemed familiar
with the problem but blamed it on Red Hat's Kernels.  They then referred
me to some performance tuning appnotes which I tried with no success.

I guess I'm off to buy a new card this afternoon - probably LSI or Adaptec.
