Package: linux-image-4.17.0-0.bpo.1-amd64 Version: 4.17.8-1~bpo9+1 Boot of my Acer C740 hangs after upgrade of Linux kernel from linux-image-4.16.0-0.bpo.2-amd64 to linux-image-4.17.0-0.bpo.1-amd64. Hang happens after console message telling that disk sd has been stopped. My Debian is version 9 except of this linux-image package from backports. Boot using linux-image-4.16.0-0.bpo.2-amd64 works fine.
