You are right, a public bug list would be very useful, maybe Ian or I could put together a short list on the wiki in the next few days. Currently we only know about these warning and the mmc bug on the Linux side. On the Xen side we have seen problems on the Arndale board with this patch: http://marc.info/?l=xen-devel&m=136120343427481 We also know that we have a few SMP bugs in the hypervisor but Ian is already working on a fix.
