Actually, I have some 9500s that are finally getting stable. Each new
driver revision and each new firmware is better than the last and by
now, I have no issues (also running the x86_64 but on amd hardware).
Anyone who asks me, usually gets a 8500 controller as recommendation
because unlike the 9500s, those are actually rock solid. You should
try the firmware updates and maybe the driver (if there is one newer
than the one in the kernel you're running) and see if you can't get
your box stable that way - as I said before, it worked for me.
Also, you might want to get an AMD system next time if you have heavy
IO and more than 4GB ram - the AMD iommu requires no bounce
buffers...

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.
