I have experienced the same kind of data corruption as you on both 6.2-RELEASE and Ubuntu 7.04 on two different machines, one P3 and one P4. The card seems to be doing naughty things to the PCI bus under load; your dmesg ought to be full of PCI timeouts. If you grep the old mailing lists for the PCI timeout errors that are produced, you'll find some messages indicating that the hardware is flawed. This seems to be worked around in the driver for Windows, since the same card, disks and machines work flawlessly on Windows 2003. -- Lars Viklund ------------------- To make it is hell.
