I also experienced the same problem. Hardware is a B&R PPC2100 Intel Atom E3815
Debian 8.8 amd64 freezing @ "dpkg something" during software installation Debian 9.1 amd64 freezing @ "discover" during software installation I changed two things before it worked (after trying and searching 2 hours): - Disabled AHCI in BIOS - Used the "firmware" version of the iso Hopefully this saves someone some trouble :-)
