Note the different API version.

Steps to reproduce

Use affected hardware and update to affected 18.09 version.

Technical details

I'm testing with the update to firmware-linux-nonfree reverted and will report.

I had to revert fbb7dbdb95d04f1517ec8011a3332a8c4c0e86e6 and 7cf770ca93cad1b3c3bb464fd4e58db79419ac25.

Seems to be this debian bug: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=903437 In short: The new package is currently unusable for my system.

D'oh, sorry. FWIW seems to work for my QCA6174, bummer broke QCA9377 :(.

tokudan commented 5 years ago

@dtzWill No hard feelings from me, updating things in general is good and NixOS allows a quick and reliable undo :)

fpletz commented 5 years ago

Seems a recent linuxFirmwareNonfree should fix that issue according to the Debian bug. Since we have at least that version on 19.03 and we're not maintaining 18.09 anymore I think we can close this.
