I'm not aware of anybody in our team having hardware where they can reproduce this issue, else I'm sure they would have already provided feedback here. There are also not many reports here of people running into this problem. Thus I assume it needs a special (and probably rare) hardware combination to trigger this. One thing I can add is that I have been running software raid1 with Xen on two SATA SSDs on an Intel CPU since many years without seeing any data corruption. As Debian packages versions of xen, linux, etc. have changed a bit since the last time this issue was reported as reproduced in this bug, it would be good to get confirmation the problem is still there in Debian unstable or testing.
