This data is old, i mean I already did that, when I pub back the K7V on
line I'll do more tests.
Sorry I can't remember which is the good one and which tha bad. I saved
them only to diff them. Full output "A" is:

I believe "A" is from a stopped state, "B" a working one, but I can't
tell for sure. More to come when the K7V is up again.
[ output is produced with via-diag -aa -ee -m ]
I patched via-diag.c to recognize the chip:
