Jeff, Tejun,
Our RHEL5-based OpenVZ linux kernel reports about SATA-related issues:
VIA VT6420 SATA RAID Controller on MSI motherboard, x86_64 kernel based on latest RHEL5 kernel,
On booting hardware initialized properly and all works fine some time, but then it detects timeout and disables devices. We have replaced SATA cables, but issue didn't go away and still present.
I've googled and found similair bugreport in linux-ide@
http://www.mail-archive.com/linux-ide@vger.kernel.org/msg060 11.html
Are you know something about this issue? I've seen that you have fixed SATA reset procedure recently, probably this issue was fixed already?
thank you,

Jeff,
In the meantime I've taken that disk out of use (although it is still in
that same machine and connected). So I can easily run tests on it.
I'm not sure I want to build my own (somewhat recent) kernel, because
that machine serves as our home server. It takes some engineering to
find time where the family is gone and nobody needs it.
Also it uses xen and I don't know whether I can find the proper patches
to get it to compile (I find it difficult in debian to find the patches
that were used to produce a kernel). But if nobody uses it, I could do
with a xen-less kernel. Hopefully bonnie or somesuch will make the
problem appear.
Like Vasily I also had it connected to the VIA controller. But the
problems also appeared when the disk was connected to the Promise
controller on the same board. So I would, at first sight, not consider
this a controller issue.

I've reproduced this issue. But on this kernel EH works well and node is still alive:
