Very interesting reading - thanks for the link. Some of those posts suggest that the newer 3Ware firmware may "improve" the issue. Otherwise, I guess I'm in the market for a different 4 channel RAID 5 SATA card. Any recommendations?
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.
