Hopefully you keep the previously working kernel around when you try a new -rc. ;) > Even the old firmware works at least for some time. Now seriously, as I said before, -21 is expected to work, but we don't really do much testing with older firmwares after we released new ones. We already have two newer versions in linux-firmware.git[1], -22 and -27. I have checked it a bit further and I see that we even stopped supporting firmwares older than -22 [2] (since 4.9-rc1). But it seems that I made a mistake in that patch and use -17 for all NICs, while it should have been -17 for older NICs and -22 for newer ones... I'll send a patch to fix that. > > Hope this helps.

Please let us know if you find any issues with it.
