I was going through logs for the last night and noticed something:
Currently I have only 7 disks connected to 6081 controller, port 5 is
free, and now stalls have been happening only on ports 0, 2 and 3. So it
seems something on high port is affecting corresponding lower port too.

As mentioned earlier, 33MHz, 66MHz and 133MHz. Motherboards are: some
Asus board with VIA chipset, Supermicro P4SCI and Supermicro X7SBE. I
think P4SCI has 66MHz 64bit PCI, not PCI-X.
