--- Comment #7 from Adrian Chadd <adr...@freebsd.org> ---
God damnit, okay. So it /looks/ like a single bit corruption of the RSC, which
causes the AES-CCM code to consider everything afterwards to be a replay
attack.

ie:

Adrians-MacBook-Pro:~ adrian$ perl -e 'printf "%x\n", 3407656;'
33ff28
Adrians-MacBook-Pro:~ adrian$ perl -e 'printf "%x\n", 2150891303;'
8033ff27

Those are from your AES-CCM replay logs.

I would've thought that a single bit error would've been caught by the MAC
CRC/FCS.
