Hi Lee, thanks for this - I'm not clear on how the channel error gets
triggered, points to an EU, and all of this without a referencing a
current descriptor.  How did you run into this case?  Assuming one does
get propagated back, what error status does the callback receive?
afaict, interrupt mitigation should not be intervening in this case.
