Hi, I have an external enclosure based on the SiI 4726 connected to the 3531 controller. It mostly works on a Debian 2.6.22 kernel patched with libata-tj-2.6.22.1-20070808. But occasionally under high load there are timeouts. Usually, the system recovers without a problem but once a disk wasn't found after the reset. It took a power off/power on of the device. Another weird problem is that the SiI 4726 software doesn't find its controller, although the config disk is found by the system. I was going to use the device in JBOD mode anyway so this isn't a big deal. Thanks for a great job. It's amazing how well this works already. I see on the SiI site they distribute a kernel module for Suse/Redhat for the 3531. Is the source available for it and does it work better with it?
