Hi Martin,

Thanks for the ack and the extra background info. I would love to take a
look at a race-free version of admac_cyclic_read_residue() as a separate
follow-up patch; v2 of this fix follows shortly. A complete test setup
is ready on my machine that traces every position read and logs the raw
registers. If you have any pointers on how REG_DESC_RING behaves, or
already have a direction in mind, that would help.

Best regards,
Jacob
