I found that the ST31500341AS has firmware issue: http://www.avsforum.com/avs-vb/showthread.php?t=1080005. So I check the /var/log/message and lsscsi, there are 2 firmware version in the server, and all sdX error messages loged are version SD17. The SD17 version should be upgrade to SD1B, or it will hung IO for almost half a minute randomly. Oct 29 08:27:21 XEN-ST-27 kernel: mptscsih: ioc0: attempting task abort!

I've apply this patch http://lkml.org/lkml/2010/4/26/335 in 2.6.18-xen with mpt version mptlinux-3.04.01, and "task abort" still show in dmesg. But smartctl -a will not trigger error even without this patch. So I think havey IO hung issue may be caused by seagate firmware and ATA path-through bug in the kernel. I didn't find ATA path-through issue in 2.6.18-xen and 2.6.16-xen, but 2.6.29 and 2.6.31 and 2.6.32 have this issue. It could be reproduced easily by running "while true; do smartctl -a /dev/sdd > /dev/null; done". Even apply patch http://lkml.org/lkml/2010/4/26/335, and try all mpt fusion driver I can find form 3.04.01 to the latest lsi version 4.0.22. Finally I test 2.6.36, ATA issue seems solved. But it doesn't support xen dom0, I can't test this kernel in productive server. I'am trying reproduce IO hung issue in lab, and upgrade seagate firmware version to verify it.
