Hi Julien,

Thanks for the report.

Vincent,

Andreas mentioned a couple of times in the mailing list the intention of
pushing a new version down to jessie-backports. Do you know which one he
intended? Do you think it could be a problem for the legacy-340xx split
process if 340.76-5 was uploaded to backports? Should instead a bpo
rebuild of 340.65-2 with the dkms fixes be uploaded?

We should probably fix 304xx as well, since it's available in Jessie,
Stretch and Sid. I'll have a look later tonight.

Kind regards,
Luca Boccassi
