It looks like the last related work was the series http://lists.xenproject.org/archives/html/xen-devel/2014-12/msg00770.html back at the end of 2014 and I'm wondering if there are any plans to revive the series. The error with swiotlb has caused us a massive amount of problems. We set swiotlb=32768 on one server and are still seeing this error message on occasion. If there's anything I can do to help please let me know. --Sarah
