Target systems have A2SDi-8C-HLN4F motherboards each with 4 no. Intel x553 NICs.
The stable netinstall ixgbe module does not load the interfaces, even when modprobed by hand. Buster netinstall 20190429-03:57 works fine. However I can't find a way of downgrading the installation to "stable", as suggested at https://wiki.debian.org/DebianInstaller/FAQ#Q:_How_can_I_install_sid_.28unstable.29_with_DebianInstaller.3F I've tried expert mode in both console and graphical mode. I'm not sure if the inability to downgrade the installation is a bug or policy. If the former I'm happy to report it. Tips on compiling the ixgbe module for stable on a machine with only a BMC and no NICs gratefully received; else how to downgrade a testing netinstall to stable. Thanks very much Rory
