Hi,

dahdi-firmware-nonfree current fails to reproduce:

https://reproduce.debian.net/all/#dahdi-firmware-nonfree

From my analysis this is due building in a non clean build environment.
As the package is arch:all and XS-Autobuild is not set we can't simply
binNMU it. Please upload a new source and binary package build in a
clean environment, for example with sbuild.

Also maybe consider adding XS-Autobuild.

Thanks!

Jochen
