Hi all,
These are all very wonderful connection! Having said that, core@ is not
an appropriate list for this thread (core@ is for core working group
business and is not a public list).
Instead, devel@ might have been a fine jumping off point and
verification(a)lists.tockos.org (now CC'd instead of core@) is best!
Go forth and prove stuff!

I believe the other areas of focus are context switch code and DMA, but I'll leave status/details/etc up to the verification team.
