It seems pretty much the same "signature" as the CS dump I had attached.

The CS dump is written in your dmesg log or systemd journal if I remember
correctly.

On my side, I've been playing with a 3.16 with the patch applied and I've been
unable to get a Packet0 error. So, it seems to have been introduced somewhere
between 3.16 and 3.17-rc7. I'll try to bisect as soon as I'll have time (maybe
not before next week).
