Understood. One result since that mail, since it closes the observation
I said I could not place: on a healthy link HISR0 carries the same
unmasked bits while interrupts keep being delivered and the BE ring was
empty at every sample. So those bits are set in normal operation and do
not hold off the edge-triggered interrupt. Not a lead.

Group 2 as you put it. Group 1 with one qualification: the raised flag
is a later stage of that group rather than the whole of it. Most of the
stalled-ring captures were taken while the ring was still filling and
the flag was not set yet; it was set in a minority, where the ring had
reached the stop threshold. So the patch covers the end state of group
1, not group 1.
