This was the original mail:
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?

I haven't tested the disks out of the enclosure so I don't know if
they work well with NCQ without PMP. I can't move other disks to the
enclosure to test because all of the disks internal in the machine are
in an LVM needed to boot.
Most of the time there's just the timeout which is bad for performance
but occasionally one of the disks doesn't come up and then I have to
rebuild the array.
