Emmanuel, I'll test the -9.ucode ASAP. Are there any bits from 3.14 or 3.15 that should be backported in order for the Ubuntu 3.13 kernel to work best with the -9.ucode?
System76 customers are experiencing a lot of problems with 7260/3160 cards, and so we're keen on getting -9.ucode in a linux-firmare SRU, assuming that's the correct fix. Interestingly, -8 seemed to work much better on our products than -7 does, which I guess could be related to a lot of factors (different antenna designs, different card revisions, different APs, etc). For us, reverting to -7 seems to create problems similar to those that people are here attributing to -8.
