Installing a basic Linux dist goes fine, basic read/write is fine. Whenever I try to read from any of the disks behind the 3ware controller with dd (dd if=/dev/sda of=/dev/null) dd will stop at approximately 1.2GB with an IO error (tried the same on multiple disks, this happens with all of them and the IO error occurs between 1.2 and 1.8GB with 1.2GB being the most common case), When the IO error shows up the kernel log gets immediately filled with the following messages: Feb 22 01:16:02 newbox kernel: 3w-9xxx: scsi0: ERROR: (0x06:0x000C): PCI Parity Error: clearing. Feb 22 01:16:02 newbox kernel: 3w-9xxx: scsi0: ERROR: (0x03:0x0212): PCI bus parity error:. Feb 22 01:16:13 newbox kernel: 3w-9xxx: scsi0: ERROR: (0x06:0x000C): PCI Parity Error: clearing. Feb 22 01:16:13 newbox kernel: 3w-9xxx: scsi0: ERROR: (0x03:0x0212): PCI bus parity error:. Sometimes it would lead to a system crash with no other messages printed. I have tried kernels 2.6.15-rc5 and 2.6.15.4 so far and both have failed with the same symptoms. I have tried using the very latest 3ware driver release, 9.3.0.3 and several of the more recent firmware versions for this card with the same results. Any hints are greatly appreciated!
